Custom Military Medals & Challenge Coins — Honor Cast in Metal
A military challenge coin is not a promotional trinket. It carries the weight of service — literally, at brass 8.9 g/cm³, 33% heavier than commercial zinc coins. Our 0.5–2mm 3D relief captures every detail of unit insignia: eagles' wing feathers, anchors' chain links, crossed rifles' bolts. Antique finishes darken the recesses and brighten the highlights — the coin looks like it has history, even fresh from the mint. Laser serial numbering on edge or back makes each piece accountable. Produced in a BSCI and Disney FAMA certified factory, with 8 active compliance certifications audited annually. This is not merchandise. This is military tradition, manufactured to government standards.

Who Orders Military Challenge Coins — Units, Agencies & Veteran Programs
Challenge coins are bought by procurement officers, unit funds, association treasurers and recognition program managers — each with a different approval process and a different deadline. Below are the buyer profiles we produce for most often, with the specification we typically recommend for each.
Active-Duty Units & Commands
Battalion, squadron, company and ship coins — issued on change of command, deployment, promotion and re-enlistment. The brief is almost always the same: it has to feel substantial and it has to be right the first time, because the ceremony date does not move. Typical spec: brass, 1.75 in (44 mm), antique gold or two-tone, reeded edge, sequential numbering so the command can account for every coin issued.
Veterans Associations & Reunion Committees
Annual reunion coins, membership coins and association anniversary pieces. These programs reorder every year with an updated date, which makes mold continuity the single most important factor — your mold stays in the archive and the next run matches the last one. Committees usually order in the 300 to 500 range and sell or issue the balance at the reunion.
Government Agencies & Municipal Programs
Commemorative coins for official visits, agency milestones, dedications and protocol gifts. Procurement here needs documentation before it needs samples: our factory holds BSCI, Disney FAMA, ISO 9001, Reach, RoHS, TUV Rheinland, Sedex and USJ certifications, audited annually, with certificates available for the file. Line-item quotes are issued so the purchase order can be coded properly.
Police & Sheriff Departments
Badge-shaped and shield-shaped coins for sworn personnel, academy graduation, K-9 units, SWAT teams and memorial coins honoring fallen officers. Departments tend toward darker finishes — matte black nickel with polished raised elements, or antique copper — and frequently request the badge number or end-of-watch date laser-engraved on the back.
Fire & Emergency Medical Services
Station coins, promotion coins, and class coins for newly sworn firefighters and paramedics. Designs lean on the Maltese cross, the crossed axes, or the station number in deep relief. Because these coins live in a turnout coat pocket or on a station desk, hard enamel is the practical choice — the flush polished surface stays clean where recessed soft enamel would collect soot and moisture.
Corporate Recognition & Safety Programs
Defense contractors, aerospace suppliers and industrial firms use coin programs for safety milestones, years-of-service recognition and project completion. The same production discipline applies — numbered editions, consistent annual reorders, and presentation packaging that matches the rest of the awards program. Volume usually lands at 500 to 1,000 pieces across multiple sites.
Commemorative Anniversaries & Memorial Dedications
Limited numbered editions — 001 of 500, for example — struck for unit anniversaries, battle anniversaries, ship decommissionings and memorial dedications. These are the orders where packaging matters as much as the metal: acrylic capsules, velvet boxes and wooden cases with engraved nameplates. Numbered editions should be ordered as one complete run so the numbering sequence and the finish stay uniform.
What Separates a Military Challenge Coin From a Promotional Token
Military challenge coins carry expectations that no other custom coin faces. Weight must feel substantial. Finish must look distinguished, not flashy. Edges must be precise. Surface must stay clean through handling. These four factors define whether a coin earns a place in a service member's collection or gets buried in a drawer.
Weight — Brass 8.9 vs Zinc 6.7 g/cm³
Pick up a brass challenge coin and you know it's real before you look at the design. Brass density is 8.9 g/cm³ — that is 33% heavier than zinc alloy at 6.7 g/cm³. A standard 1.75-inch brass coin weighs approximately 30 grams; the same coin in zinc weighs about 22 grams. That 8-gram difference is the gap between 'this feels substantial' and 'this feels like a bottle cap.' Brass costs 20–40% more per unit than zinc alloy, and for military and government orders, the premium is justified. Brass also accepts antique plating more richly — the darker recesses and brighter highlights that define military coin aesthetics develop deeper contrast on brass substrates. Our position: quote both materials, recommend brass for challenge coins, use zinc alloy for oversized medals where weight from brass would be impractical and die-casting complexity requires zinc's lower melting point.
Antique Finishes — Depth That Mirror Finishes Destroy
Mirror-polished gold looks great on jewelry. On a military coin with 3D relief, it flattens the design — light bounces off the raised surfaces and the recessed areas with nearly equal intensity, erasing the visual depth your mold designer worked to create. Antique finishing solves this. The electrophoresis process deposits a dark compound into recessed areas while leaving raised surfaces bright. The result: your unit crest's eagle pops forward, the crossed rifles behind it recede, and the lettering reads clearly at a glance. Antique gold, silver, copper, and bronze — each creates a coin that looks like it carries decades of tradition, not weeks of production. For commands that want a darker, more tactical aesthetic, matte black nickel with polished raised elements provides maximum contrast. Antique finishes also hide minor handling wear better than mirror finishes — a practical advantage for coins that get carried, traded, and displayed.
Edge Treatment — The Detail Most Coins Get Wrong
The edge of a coin is the first surface your thumb touches. Reeded edges (the parallel ridges you feel on a quarter) communicate 'coin' instantly — familiar, traditional, authoritative. Diamond-cut edges use a 45-degree bevel that catches light from every angle, creating a subtle glow around the coin's perimeter — especially striking on presentation pieces under ceremony lighting. Smooth edges offer a modern, clean profile that works well with edge lettering. Speaking of edge lettering: unit mottoes, dates, coordinates, or command names laser-engraved around the coin's edge are technically demanding — the engraving must wrap a curved surface with consistent depth and alignment. This is the mark of a truly custom coin, not a stock blank with a sticker. Our laser equipment runs edge engraving at 0.02mm precision, calibrated per batch. All three edge styles — reeded, diamond-cut, smooth — are available at no cost difference; edge lettering adds a small per-unit surcharge for the additional production step.
Hard Enamel — The Military Standard, Explained
Hard enamel (also called imitation hard enamel or cloisonne-style) produces a completely flush surface — the enamel fills the recessed areas of the coin exactly to the level of the metal borders, then the entire surface is polished flat. Run your fingernail across a hard enamel coin and you feel one continuous smooth plane, like a minted currency coin. Soft enamel, by contrast, leaves the enamel slightly recessed below the metal borders — you can feel the texture, and those recessed areas trap dirt, skin oils, and moisture over time. For a coin that gets handled — traded at reunions, carried in pockets, displayed on desks — hard enamel stays clean and presentable. It costs 15–25% more than soft enamel due to the additional polishing step and higher enamel fill precision required, but for military orders it is the expected standard. Hard enamel also delivers richer color saturation because the filled enamel is denser (less air trapped during filling) and the polished surface reflects light uniformly across the entire color area.
Challenge Coin Specification Matrix — Size, Thickness, Material & Edge Pairing
Diameter, thickness, alloy and finish have to be chosen together — not one at a time. Brass is stamped, and gets difficult to strike above roughly 3 mm; zinc alloy is die-cast at 385℃ and holds complex geometry with a 2 mm minimum wall. Use the matrix below to shortlist a combination before you request a quote, then we will confirm what your specific insignia can hold.
| Size Band (Diameter) | Thickness | Material Recommendation | Weight in Hand | Recommended Finish | Edge Treatment |
|---|---|---|---|---|---|
| Pocket / daily-carry coin — 1.25–1.5 in (32–38 mm) | Slim profile, at the light end of the standard band | Brass (8.9 g/cm³) or zinc alloy (6.7 g/cm³) | Lightest of the range — made to sit in a pocket without bulk | Antique copper or matte black, both forgiving of daily handling | Fine reeded or smooth |
| Standard unit coin — 1.75 in (44 mm) | 3–4 mm | Brass for weight and antique contrast; zinc alloy (Zamak 3 / 5 / 7) where the crest needs complex 3D or cut-outs | Brass reads 33% heavier than the same coin in zinc alloy — the difference you notice before you see the design | Antique gold, antique silver, or two-tone gold with nickel insignia | Reeded (traditional) or cross-cut |
| Command / presentation coin — 2–2.5 in (50–63 mm) | 3–4 mm, and up to 6 mm for oversized pieces | Zinc alloy die-cast on 88-ton machines at 385℃, 2 mm minimum wall | Heaviest in-hand weight of the standard range — substantial for a two-hand presentation | Antique gold with dual-plated crest; rainbow vacuum plating for special editions | Diamond-cut or rope edge |
| Display / wall piece — 3 in and above | 6 mm and above | Zinc alloy — brass becomes impractical to strike at this thickness and volume | Heavy by design; this is a case or wall piece, not a pocket piece | Antique bronze or matte gold, with deep recessed areas for contrast | Smooth, with laser-engraved edge text |
| Shield, crest or fully custom outline | 3–4 mm, 2 mm minimum wall for die-cast | Zinc alloy die-cast — irregular outlines need the flow of 385℃ zinc | Balanced; the silhouette carries the design rather than the weight | Any antique finish, with hard enamel for branch colors | Smooth outline following the shape |
Customization Options — Make Every Coin Unmistakably Yours
Dual-Plating
Gold body with nickel (silver) insignia — or vice versa. The unit crest rendered in bright nickel against an antique gold background creates instant visual hierarchy. Masking during the plating process isolates each finish to its designated area. Small per-unit surcharge for the additional plating step and masking labor. Popular for command coins where the insignia must stand apart from the field.
Serial Numbering on Edge
Laser-engraved sequential numbers around the coin's edge — each coin individually marked and traceable. Common for numbered edition command coins (e.g., 001/500), retirement presentations, and commemorative pieces. Variable data from your roster file (Excel/CSV) — names, ranks, dates, unit designators. Edge numbering preserves the back design for full artwork.
Custom Edge Text — Unit Motto
Your unit motto, deployment dates, geographic coordinates, or command name engraved around the coin's edge. Laser precision at 0.02mm accuracy. Common choices: SEMPER FIDELIS, DE OPPRESSO LIBER, THIS WE'LL DEFEND, or custom Latin mottoes. Edge lettering identifies the coin even when face-down — a mark of a fully custom piece.
Presentation Cases
Velvet pouches (included standard with every coin). Upgrades: rigid velvet gift boxes with satin lining, acrylic display capsules with black base, wooden display cases with engraved nameplates, and custom foam inserts cut to the exact coin profile. Each option quoted separately. Military ceremonies deserve presentation packaging that matches the weight of the moment.
3D Relief up to 2mm Depth
Maximum sculptural depth for dramatic unit insignia. Eagles with outstretched wings that rise 2mm from the coin surface. Anchors, swords, and crests rendered in deep relief you can feel with your thumb. Die-casting and stamping both achieve this depth — the material choice (brass vs zinc alloy) determines which production method applies. Discussed during design review.
Rainbow / Iridescent Plating
A specialized electroplating process that produces a spectrum of colors shifting across the metal surface — gold to purple to blue to green depending on viewing angle. Popular for special operations unit coins, aviation squadron pieces, and commemorative editions. More delicate than traditional antique finishes; recommend acrylic capsule presentation to protect the surface.
Factory-Direct — What That Actually Means for Military & Government Orders
Military & Government Experience
We have produced challenge coins, unit medals, and commemorative pieces for military commands, government agencies, law enforcement departments, and veterans' organizations across multiple countries. Our team understands military design language — heraldry, insignia hierarchy, branch-specific symbolism, and the unspoken rule that a military coin must feel like it means something. We speak your language: battalion, squadron, detachment, command. We understand the difference between a company coin and a division coin, and we'll size and spec accordingly.
BSCI & Disney FAMA Certified — 8 Active Certifications
Our factory holds 8 active compliance certifications audited annually: BSCI (Business Social Compliance Initiative — ethical manufacturing, labor standards, workplace safety), Disney FAMA (Facility and Merchandise Authorization — supply chain security, product safety, ethical sourcing), ISO 9001 quality management, and additional environmental and social compliance standards. For government procurement officers: these certifications mean audited supply chain transparency, documented quality control procedures, and verified ethical manufacturing. Certificates available for review upon request.
Mold Ownership — Your Mold, Your Property, Never Reused
When we cut a mold for your unit coin, that mold belongs to you. Period. It is labeled with your unit designation, cataloged, and archived in our secure mold library. It will never be used for another client's order. It will never be shown to another client as a sample. When you reorder next year — updated date, same design — we retrieve your mold, produce your coins, and return it to archive. If you ever want your mold shipped to you or destroyed, we'll provide documented confirmation. This is non-negotiable. Military coins carry unit identity; that identity is not for sale to anyone else.
Plating & Finish Comparison — Choosing the Surface for Your Unit Coin
The finish does more than set the color. It decides how much of your 3D relief the eye can actually read, how the coin behaves under ceremony lighting, and how well it hides the wear that comes from being carried and traded. Every finish below runs through the same plating line — an alkaline copper base of roughly 500 seconds, an acid copper gloss bath of 20 to 60 minutes, color plating, and a tunnel oven at 100℃ for 40 minutes. The antique effects are then developed by electrophoresis, which deposits into recesses the way dipping never can.
| Finish | How It Reads | Durability & Upkeep | Best Use Case |
|---|---|---|---|
| Antique gold | Dark compound settles into the recesses while raised surfaces stay bright — the crest moves forward and the field recedes. The default military look. | Hides fingerprints and minor handling wear better than any mirror finish. Gold is sealed with a protective oil to slow oxidation. | Unit coins, command coins, change-of-command presentations — any piece with 3D relief that needs to read at a glance. |
| Antique silver / antique tin | Cool grey-silver with darkened recesses. Crisper and more formal than gold, and unusually sharp under ceremony or stage lighting. | Electrophoresis covers hidden and recessed areas completely, so the contrast holds on fine detail. Sealed and oven-cured on the same line as the other antique finishes. | Navy, Coast Guard and Air Force palettes; protocol coins; pieces photographed for official release. |
| Antique copper | Warm red-brown with a lived-in patina. Develops more character the more it is handled rather than degrading. | Sealing oil is recommended and applied as standard on copper tones to prevent oxidation. Patina variation between pieces is normal and expected. | Artillery, armor, cavalry and Marine heritage coins; retirement coins; anniversary editions. |
| Matte black | Fully non-reflective. Nothing competes with the raised elements, so polished insignia against a black field gives the strongest contrast available. | Best fingerprint resistance of any finish. Matte surfaces should not be polished or buffed by the recipient — cleaning is a soft dry cloth only. | Special operations and tactical unit coins, K-9 and SWAT coins, memorial pieces. |
| Matte gold / matte silver | Satin, low-glare versions of the classic tones. Reads as modern and institutional rather than ceremonial. | Soft finish shows abrasion more than antique finishes, so it suits coins that are presented and displayed rather than carried loose. | Corporate recognition programs, agency milestone coins, pieces displayed under glass. |
| Two-tone (gold + nickel) | A gold field with the insignia rendered in bright nickel — or the reverse. Creates instant visual hierarchy without adding a second color of enamel. | Requires masking between plating steps, so it carries a small per-unit surcharge. The masked boundary is durable and will not flake under normal handling. | Command coins where the crest must separate cleanly from the background; coins with a single dominant central emblem. |
| Rainbow vacuum plating | A vacuum-deposited spectrum that shifts gold to purple to blue to green with the viewing angle. No two pieces look identical. | The most delicate finish we run. Recommend acrylic capsule presentation and minimal direct handling to protect the surface. | Aviation squadron pieces, special operations editions, numbered collector runs. |
Cost runs plating, then painting, then electrophoresis — so an antique effect is not automatically the expensive option. Tell us the look you want and the budget you are working to, and we will quote two finishes side by side.
Order Quantity, Tooling & Lead-Time Planning
Quantity does not change the front end of a coin project — design, mold cutting and proofing take the same time whether you order 100 or 5,000. What changes is the production window and the unit price. The table below is the planning reference our institutional buyers use to set a ceremony date backwards.
| Order Size | Tooling | Design & Proof | Sample | Mass Production | Planning Note |
|---|---|---|---|---|---|
| 100 pcs — MOQ per design | New mold cut, labeled with your unit designation, archived as your property | Free design and 3D renderings within 24 hours | 7–10 days; photo and video confirmation standard, physical sample on request | 7–15 days after approval | Entry tier. Correct size for a squadron, a small association or a single presentation set. |
| 300 pcs | Same mold, single run | Free design and 3D renderings within 24 hours | 7–10 days | 7–15 days after approval | First volume pricing tier; the most common size for reunion and association coins. |
| 500 pcs | Same mold, single run | Free design and 3D renderings within 24 hours | 7–10 days | 7–15 days after approval | Natural size for a numbered edition (001/500). Numbering adds one laser pass, not extra calendar time. |
| 1,000 pcs | Same mold; plating scheduled as a dedicated bath | Free design and 3D renderings within 24 hours | 7–10 days | 7–15 days after approval | Typical battalion-level issue plus spares for replacements and visiting dignitaries. |
| 5,000+ pcs | Same mold; production distributed across die-casting and plating lines | Free design and 3D renderings within 24 hours | 7–10 days | 7–15 days after approval, scheduled in sequence | Well inside our 30,000+ pcs/day output. Division-level or multi-site distribution programs; every batch still passes the same 3-stage QC. |
Factory reference for procurement files: founded in 2010, 15+ years in metal award manufacturing; daily output above 30,000 pieces; exports to 50+ countries; free in-house design with artwork inside 24 hours and unlimited revisions; 7–15 day mass production; and a 3-stage quality control process covering casting, plating and color filling before packing. Certifications audited annually: BSCI, Disney FAMA, ISO 9001, Reach, RoHS, TUV Rheinland, Sedex and USJ. Production runs from our plant in Huizhou, Guangdong. Because your mold is archived under your unit designation and never used for another client, a reorder next year is a retrieval, not a re-tooling — and the coins match the original batch.
Military Challenge Coin FAQ — Straight Answers From the Factory Floor
Zinc alloy or brass — which should I choose for my unit coin?
Brass for challenge coins. At 8.9 g/cm³ it is 33% heavier than zinc alloy (6.7 g/cm³), and that weight difference is the first thing anyone notices when they pick up the coin. Brass also accepts antique finishes with richer contrast. Zinc alloy is better suited for large medals (3 inches and above) where brass would be too heavy and expensive. We quote both materials so you can compare cost vs feel directly. Most military commands choose brass for coins and zinc alloy for oversized presentation pieces.
Can you do dual-plating — gold and silver on the same coin?
Yes. Gold body with nickel (silver) insignia is the most common military request — the unit crest stands out clearly against the background. The process involves masking the areas that should remain the first finish, applying the second finish to the unmasked areas, then removing the mask. A small per-unit surcharge applies for the additional plating step and masking labor. Dual-plating works especially well on coins with a central crest or badge element.
What are the standard challenge coin sizes?
1.75 inches (44mm) is the most common challenge coin size — palm-sized, substantial without being bulky. 2 to 2.5 inches (50 to 63mm) for presentation and command-level coins — the extra diameter gives more surface area for complex insignia and engraving. 1.25 to 1.5 inches (32 to 38mm) for pocket coins — designed to be carried daily. Standard thickness is 3 to 4mm; oversized presentation coins can go up to 6mm for maximum heft.
Can each coin have a unique serial number?
Yes. Laser engraving on the coin edge or back surface. Sequential numbering (001 through 500) or custom variable data from your provided file — names paired with numbers, ranks with dates, any alphanumeric format. Edge numbering keeps the coin face clean for design while marking each piece individually. Back engraving allows longer data strings. Data programming setup is a one-time per-order cost; per-unit engraving cost is minimal.
Do you offer presentation cases for military coins?
Yes. Every coin order includes individual velvet pouches as standard. Upgrades available: rigid velvet gift boxes with satin interior lining, clear acrylic display capsules with black base stands, wooden display cases with engraved nameplates, and custom-cut foam inserts that hold the coin securely. Each presentation option is quoted separately based on quantity and specifications. For military ceremonies and retirement presentations, velvet boxes and wooden cases are the most popular choices.
Is the mold reused for other clients' orders?
No. Your mold is your property. It is cut specifically for your unit's design, labeled with your unit designation, and archived in our secure mold library. It is never used for another client. It is never shown to another client as a sample. When you reorder, we retrieve your mold, produce your coins, and return it to archive. If you ever request the mold be shipped to you or destroyed, we provide documented confirmation. Unit identity is not for resale.
Can you match an existing coin we already have?
Yes. Send us the original coin or clear photographs with a ruler for scale reference. We will reproduce the design — same size, shape, relief details, plating, and enamel colors — and in most cases we can improve it: deeper 3D relief, sharper edge definition, richer antique finish, or upgraded hard enamel. We will also quote any improvements separately so you can decide what to upgrade. Many commands come to us specifically because their previous supplier's quality declined, and they need a consistent replacement.
What is the typical turnaround for military coin orders?
Standard production timeline is 3 to 4 weeks after sample approval. The process: 24 hours for free design and 3D renderings, 7 to 10 days for a physical pre-production sample, and once the sample is approved, 2 to 3 weeks for full production plus shipping time. Rush production is available at 2 to 3 weeks total when materials are in stock and the plating schedule has capacity. For time-sensitive orders — change of command ceremonies, deployment departures, Veterans Day events — tell us your deadline in your first message and we will confirm what timeline is achievable.
What is the minimum order for custom military challenge coins?
100 pieces per design. One design means one artwork, one finish and one size — the same crest struck in two finishes or two sizes counts as two production runs. Unit price steps down at 300, 500, 1,000 and 5,000+ pieces, so a battalion-level order is quoted at a materially lower per-coin cost than a 100-piece squadron order, even though both use the same mold. Because our output runs above 30,000 pieces a day, even a 5,000-piece order is produced as one continuous program rather than spread across weeks — which is what keeps the plating bath and the antique finish consistent from the first coin to the last.
How long does a 100-, 500- or 1,000-coin order take?
Every quantity moves through the same three stages: free design and 3D renderings within 24 hours, a sample in 7 to 10 days, then 7 to 15 days of mass production once the sample is approved. Quantity does not change the front end — a 100-piece order and a 1,000-piece order spend the same time in design, mold cutting and proofing. What changes is the production window inside the factory: at more than 30,000 pieces a day, 1,000 coins is a short run, while 5,000 and above is scheduled in sequence across die-casting and plating lines. Add transit time for your region — we ship to 50+ countries. If you have a hard date, tell us in your first message and we will confirm whether a rush slot is open before you commit.
Can coins be sequentially numbered, and can I get 3D relief on both faces?
Yes to both, and they are often combined on the same coin. Numbering is laser-engraved — around the edge so both faces stay clean for artwork, or on the back when you need longer data strings. Sequential runs such as 001 through 500, or variable data straight from your roster file: name, rank, dates, unit designator. Two-sided 3D relief is produced by die-casting zinc alloy (Zamak 3, 5 and 7, melted at 385℃) on 88-ton machines, with a 2 mm minimum wall thickness and typical sculptural depth of 0.5 to 2 mm. Doubling the relief doubles the mold work, so it is quoted as a separate tooling line — worth it for a coin meant to be turned over in the hand rather than laid flat in a case.
What artwork files do you need to start a coin project?
Vector files are the best starting point — AI, EPS, PDF or CDR — because insignia line work is cut straight into the mold from vector paths, and vector art scales without losing edge definition. Supply Pantone references for any enamel colors; we match to Pantone standards. Watch the fill limits: soft enamel holds detail down to 0.3 mm, while imitation hard enamel and glass enamel hold down to 0.5 mm. Text or line work thinner than that will not fill cleanly and should be thickened in the artwork stage. If all you have is a photograph of an existing coin, a unit patch or a crest sheet, send it — we redraw it as vector art for free, inside 24 hours, and nothing is cut until you approve the rendering. Full-color artwork with gradients or photography is handled by UV printing, which holds registration on relief up to 7 mm.
Die-casting or stamping — which process does our unit crest actually need?
It follows the geometry of your insignia, not a house preference. Die-casting injects zinc alloy (Zamak 3, 5 and 7) at 385℃ on 88-ton machines, so it fills complex 3D, cut-outs and irregular shield or badge outlines, and it holds a 2 mm minimum wall. Stamping strikes brass at 8.9 g/cm³ or iron at 7.8 g/cm³ from sheet stock — the right choice for flat or shallow-relief crests with clean line work, and the process behind most traditional challenge coins where weight in the hand is the point. Brass becomes hard to strike above roughly 3 mm and iron above roughly 4 mm, which is the practical ceiling. We quote both against your actual artwork so you can see the difference in tooling and unit price before you commit.
How is our mold stored between annual reorders, and what happens when the date changes?
Your mold is cut in mold steel, heat-treated for hardness and wear resistance, labeled with your unit designation and archived in our secure mold library. It is never used for another client and never shown to another client as a sample. When you come back the following year, we retrieve it instead of re-tooling, so the new batch matches the last one. A change of year or date is the most common amendment, and it is quoted as a tooling amendment rather than a complete new mold. If you ever want the mold shipped to you or destroyed, we provide documented confirmation.
What actually goes wrong on a coin run, and how is it caught before shipping?
The faults worth understanding are the ones that appear in the metal rather than in the artwork. Cracks come from too few ejector pins or pins distributed unevenly, so the casting is pushed out of the mold under uneven force. Flow lines come from a cavity that is not polished enough, insufficient machine pressure, or a shot fired too fast. Porosity means the mold is not venting properly. Sharp corners that fail to fill mean the pressure is too low for that part. Plating blisters trace back to parts that were not cleaned properly before the bath, or to sealing oil baked before the part was fully dry. Every order passes three inspection gates — after casting, after plating and after color filling — before it is packed. Send us the sample photographs you are comparing against and we will tell you which of these to look for.
Can you supply the compliance documentation our procurement office needs?
Yes, and it is better to request it at quote stage than at purchase-order stage. Our factory holds ISO 9001 quality management, BSCI, Sedex, Reach and RoHS, audited annually, alongside Disney FAMA and additional environmental and social compliance standards — 8 active certifications in total. Certificate copies are issued with your quote so the procurement file can be built before you commit budget. We also issue line-item quotes, with the mold fee, unit price, plating, numbering and packaging broken out separately, because institutional purchasing usually has to code each line against its own budget heading.
If we reorder next year, do we have to order another 100 pieces?
The 100-piece minimum applies to a production run, not to the mold. Your mold stays in the archive under your unit designation whether you order 100 or 5,000, so an annual reorder never carries a new tooling line — the year or date change is quoted as a tooling amendment instead. If you need a short top-up, tell us the quantity in your first message and we will confirm whether it can be scheduled as a shorter run alongside other work on the die-casting line. Most annual programs simply reorder at the tier they used the first time, because unit price steps down at 300, 500, 1,000 and 5,000+ pieces and the per-coin difference across those tiers is usually larger than the saving from ordering fewer.
Can we have dual-plating and an antique finish on the same coin?
Yes, and it is one of the strongest combinations for a command coin. The sequence matters: the coin is plated, then the antique effect is developed by electrophoresis, which deposits into the recesses and leaves the raised surfaces bright. Dual-plating adds a masking step so one area takes gold while another takes nickel, and the antique pass then runs over both — the result is a gold field with a nickel crest, each reading at a different depth. Because the two finishes meet at a masked boundary, keep that boundary on a raised metal line rather than on a flat field, so the transition reads as a design feature rather than a seam. A small per-unit surcharge covers the masking and the second plating step; the antique pass is priced on the same line as any other antique finish.
Where should the serial number go if both faces are already full of artwork?
On the edge. Laser engraving around the rim leaves both faces entirely free for the crest, which is why it is the placement most commands choose — the coin reads as a designed object face-on and only reveals its number when you turn it over. If the rim is already carrying edge lettering, the alternative is a small flat panel on the reverse, kept clear of the relief at the artwork stage; that is the placement to use when you need longer strings such as a name paired with a service date. Both placements read from the same roster file, so specify which one you want on the drawing rather than after the sample arrives.
How are the coins packed, and what documents come with the shipment?
Every coin is packed individually in a velvet pouch as standard, then cartoned, with the piece count per carton recorded on the packing list. Upgrades — rigid velvet boxes, acrylic capsules with black base stands, wooden cases with engraved nameplates, or custom-cut foam inserts — are packed to the same count and quoted separately. Shipment paperwork covers the packing list and the commercial documents your import process requires, prepared for the country you are shipping to; we export to 50+ countries. If your receiving office needs certificate copies, a QC record or a country-of-origin statement collated with the shipment rather than with the quote, ask for it when you approve the sample and we will assemble it before the cartons leave Huizhou.

Die-Casting vs Stamping — Which Process Your Unit Crest Actually Needs
Almost every military coin and commemorative medal is made one of two ways, and the choice is decided by geometry rather than by preference. Die-casting injects molten zinc alloy into a closed mould; stamping strikes brass or iron from sheet stock. This is the comparison we run against your actual insignia before we quote a tooling figure.
| Decision Factor | Die-Casting — Zinc Alloy | Stamping — Brass or Iron |
|---|---|---|
| Alloy and equipment | Zinc alloy Zamak 3, 5 and 7, melted at 385℃ and injected on 88-ton die-casting machines | Brass at 8.9 g/cm³ or iron at 7.8 g/cm³, struck from sheet stock and then cut to outline |
| Designs it suits | Complex 3D, cut-outs and openwork, irregular shield or badge outlines, two-sided relief | Flat or shallow-relief crests with clean line work; traditional struck coins and pocket pieces |
| Relief capability | Sculptural depth in the 0.5–2 mm band, with the undercut a mould can release | Shallow to medium relief; brass becomes hard to strike above roughly 3 mm, iron above roughly 4 mm |
| Thickness limit | 2 mm minimum wall — the alloy has to flow through the cavity before it freezes | Thicker stock is possible, but the strike pressure required climbs steeply with thickness |
| Tooling | Mould steel, cut from a 3D engraving programme, then heat-treated for hardness and wear resistance | Striking die and blanking tool cut from the same approved artwork |
| Unit price behavior | Lower alloy cost, and the strongest unit price once the run reaches volume tiers | Higher alloy cost on brass; competitive where the design is flat and the run is modest |
| Lead time | Free design and 3D renderings within 24 hours, sample in 7–10 days, then 7–15 days of mass production | Identical front end and identical production window — the process choice does not change the calendar |
| Reorders | Your mould is labeled with your unit designation and archived; a reorder is a retrieval, not a re-tooling | Same custody rule: your tooling is your property and is never used for another client |
The practical shortcut: if your crest has elements that stand proud of the field with air behind them, die-casting is almost always the answer. If it reads as a clean badge with line work and flat color areas, stamping gives you the weight brass is chosen for. We will quote both and put the two numbers side by side.
Inside the Plating Line — Stage-by-Stage Specification
Two different lines finish a military coin. The electroplating line builds the metal finish; the electrophoresis line develops the antique effects that make relief readable. Both are run in-house, and the parameters below are the ones our line actually works to.
Electroplating sequence
| Stage | What Happens | Why It Matters to a Unit Coin |
|---|---|---|
| Wax and oil removal | Polishing compounds and release agents are stripped from the raw casting | Residue left at this stage is what later surfaces as plating blisters |
| Ultrasonic cleaning | Parts are cleaned ultrasonically immediately before they enter the bath | Most adhesion failures trace back to this step rather than to the bath itself |
| Alkaline copper strike | A copper base coat deposited over roughly 500 seconds | The adhesion layer. Without it, color plating on zinc alloy lifts under handling |
| Acid copper gloss bath | 20 to 60 minutes, depending on the depth of gloss the finish requires | Turns a grey casting into a surface that will take mirror, matte or antique color evenly |
| Color plating | Imitation gold, nickel, copper, rose gold, chrome, black nickel or platinum — mirror or matte | The color your unit specified, deposited over the copper base |
| Tunnel oven | 100℃ for 40 minutes | Cures the deposit and drives off moisture before any sealing step is applied |
| Sealing oil | Gold and copper tones are sealed with a protective oil to slow oxidation | The reason an antique copper coin still holds its color after a year of being carried |
| Unload and inspect | Parts leave the line and enter the plating inspection gate | One of the three QC gates every order passes before it is packed |
Electrophoretic antique line — nine stages
| # | Stage | What It Does to the Coin |
|---|---|---|
| 1 | Degrease | Removes oil carried over from casting and polishing |
| 2 | Blackening | Grows an oxide film over the whole surface, including the recesses |
| 3 | Drying | Sets the oxide film before any mechanical work |
| 4 | Highlight brushing | Abrasive wheel work removes the oxide from raised surfaces, leaving the recesses dark |
| 5 | Racking | Parts are hung so every surface is exposed to the bath |
| 6 | Ultrasonic cleaning | Removes the swarf from stage 4 so it cannot be sealed under the coating |
| 7 | Electrophoretic coloring | Coating ions migrate under voltage and deposit on the cathode — reaching into recesses dipping cannot |
| 8 | Tunnel oven drying | Cures the electrophoretic film to full hardness |
| 9 | Unload | Parts enter the final inspection gate before color filling or packing |
Cost runs plating, then painting, then electrophoresis, so an antique effect is not automatically the expensive option. Color that has to be filled is cured on a separate schedule — a low bake at 60–70℃ for 60–90 minutes leaves the fill semi-cured for a second color or a wipe, and a full cure is 100℃ for 60 minutes. Both are run before the piece reaches the packing bench.
Artwork & File Specification — What to Send Before We Cut a Mould
Nothing is cut until you approve a rendering, but what you send determines how fast we get there. This is the checklist our design team works to on every military project — the same one we send back if a file needs correcting.
| Item | Requirement | Why It Is Specified This Way |
|---|---|---|
| Preferred formats | Vector: AI, EPS, PDF or CDR | Insignia line work is cut straight into the mould from vector paths, and vector art scales without losing edge definition |
| If you only have a raster or a photograph | Send the photo, unit patch or crest sheet with a ruler for scale | We redraw it as vector art for free, inside 24 hours, with unlimited revisions |
| Color reference | Pantone references for every enamel color | Color is mixed to Pantone standards, so a named unit color is reproducible on a reorder two years later |
| Fonts | Convert all text to outlines or curves before sending | A font that is not installed on our side substitutes silently, and the lettering shifts without anyone noticing until the sample |
| Minimum fill width — soft enamel | 0.3 mm | Below this the color will not fill cleanly; thin line work should be thickened at the artwork stage |
| Minimum fill width — imitation hard enamel, glass enamel | 0.5 mm | The thicker fill material needs a wider cell to fill and to polish flush with the metal border |
| Relief intent | Mark which elements are raised and which are recessed, against a typical 0.5–2 mm sculptural depth | Enamel sits in the recesses, so relief and color have to be planned on the same drawing, not separately |
| Variable data | Sequential numbers, names, ranks, dates or unit designators supplied as an Excel or CSV roster | Laser engraving reads the file directly; specify edge or back placement on the drawing |
| Full-color artwork | Gradients and photography are handled by UV printing, which holds registration on relief up to 7 mm | Four-color printing reproduces gradients and photographic detail that enamel fill cannot |
| Approval | A 3D rendering is issued for approval before any steel is cut | Physical samples take 7–10 days and add freight both ways; photo and video confirmation is the standard route |
Six Occasions That Carry a Military Coin — And the Spec Each One Usually Needs
Buyer type tells us how the order will be approved. The occasion tells us what the coin has to do on the day. Below are the six we produce for most often, each with the specification that tends to fit it.
Retirement & End-of-Service Commendations
The coin handed over at the end of a career. Typically brass, 1.75 in (44 mm), antique gold or antique copper, with service dates and the retirement year laser-engraved on the back. Because the recipient is named, this is the occasion where variable data matters most — send the roster file with the artwork so names and dates are engraved from one source rather than retyped.
Service Anniversary & Unit Milestone Pieces
Anniversary coins marking a founding date, a deployment cycle or a ship or squadron milestone. Numbered limited editions are common here — 001 of 500 — which should be produced as one complete run so the numbering sequence and the finish stay uniform. The year element is the part that changes, and it is quoted as a tooling amendment on the archived mould.
Police & Law Enforcement Recognition
Badge and shield outlines for sworn personnel, academy graduation, K-9 units, tactical teams and memorial pieces honoring fallen officers. Departments lean toward darker finishes — matte black nickel with polished raised elements, or antique copper — and frequently request a badge number or end-of-watch date engraved on the reverse.
Fire & Emergency Medical Services
Station coins, promotion coins and class coins for newly sworn firefighters and paramedics. Designs build on the Maltese cross, crossed axes or the station number in deep relief. These coins live in a turnout coat pocket or on a station desk, so imitation hard enamel is the practical choice — the flush polished surface stays clean where recessed soft enamel would collect soot and moisture.
Veterans Association & Reunion Programs
Annual reunion coins, membership coins and association anniversary pieces. The defining requirement is continuity: the association reorders every year with an updated date, and the mould has to produce a piece that matches the last one. Orders usually land in the 300 to 500 range, with the balance issued or sold at the reunion.
Honor Guard & Ceremonial Presentation
Pieces presented under ceremony lighting, where the finish has to read from a podium as well as in the hand. Antique silver or two-tone gold with nickel insignia gives the strongest separation under stage light; diamond-cut edges catch the light around the perimeter. Presentation packaging matters as much as the metal here — acrylic capsules, velvet boxes and wooden cases with engraved nameplates.
Common Defects on Metal Coins & Medals — Cause and How We Avoid Them
Most disappointing coin orders are not a design problem — they are a metal problem that nobody caught before packing. This is the fault list our QC team works from, published so you know what to look for when you compare suppliers or approve a sample.
| Symptom | What Causes It | How It Is Avoided |
|---|---|---|
| Cracks in the casting | Too few ejector pins, or pins distributed unevenly, so the part is pushed out under uneven force | Ejector layout is designed with the mould, and round medals are gated at four evenly spaced points |
| Flow lines or water marks on the face | Cavity not polished enough, insufficient machine pressure, or the shot fired too fast | Cavity polished to finish; pressure and shot speed set per part on the 88-ton machine |
| Porosity and pin holes | Poor venting in the mould | Venting is designed into the mould rather than corrected afterwards; castings are inspected before polishing |
| Sharp corners that never filled | Machine pressure too low for that geometry | Pressure is matched to the part, and sharp internal corners are radiused at the design stage |
| Plating blisters or lifting | Parts not cleaned properly before the bath, or sealing oil baked before the part was fully dry | Ultrasonic cleaning ahead of the alkaline copper strike; the tunnel oven cycle completes before sealing |
| Streaking across the plated surface | Insufficient bath agitation, or excessive organic contamination in the solution | Bath agitation and solution filtration are maintained on the plating line |
| Specks and dirt in the enamel | Poor cleanliness in the color-filling booth | Color filling is carried out in a controlled booth, with parts cleaned immediately beforehand |
| Bubbles in the enamel fill | Part not cleaned, or air in the paint or the applicator | Parts cleaned before filling; paint and tools de-aired before the run |
| Dirt spots under the paint | Part not cleaned before painting | A dedicated cleaning step sits in front of every painting operation |
| Runs or sagging in the coating | Both faces painted in one pass, so the coat builds locally | One face at a time, with coat thickness controlled between passes |
| Dense pin-holing in a sprayed coat | Moisture in the compressed air, or the wrong thinner for the system | Moisture traps on the air line, and the thinner specified for the coating system in use |
| Color that stays soft or marks easily | Bake left short of full cure | Low bake at 60–70℃ for 60–90 minutes when a second color or a wipe follows; full cure at 100℃ for 60 minutes |
Every order passes three inspection gates — after casting, after plating and after color filling — before it reaches packing, on a line running above 30,000 pieces a day from our plant in Huizhou, Guangdong. Ask for the sample photographs at each gate; we send them as standard.
Keep Planning — Quality, Pricing & Adjacent Categories

Challenge Coin, Military Medal or Unit Pin — What One Budget Actually Buys
Commands rarely buy only one thing. The same unit fund that pays for a change-of-command coin usually also has a formal award to present and a pin for daily wear. These three objects are made on the same equipment, from the same alloys, under the same 100-piece-per-design rule — but they are specified differently, and picking the wrong one is the most common way a recognition budget gets spent twice.
| Decision Factor | Challenge Coin | Full-Size Military Medal | Unit Lapel Pin |
|---|---|---|---|
| What it is actually for | Recognition that is carried, traded and handed over — the object is the gesture | Formal recognition presented, worn on parade or mounted for display | Daily identification worn on a lapel, cover or uniform |
| Size band | 1.25–2.5 in (32–63 mm), thickness 3–4 mm and up to 6 mm for oversized pieces | 3 in and above, where die-cast zinc alloy carries the weight brass cannot | Cut to the crest silhouette, thin section by comparison |
| Process | Stamped brass at 8.9 g/cm³ for weight, or die-cast zinc alloy for complex 3D | Die-cast zinc alloy on 88-ton machines at 385℃, 2 mm minimum wall | Die-cast or stamped, then finished with the same plating line |
| How it is carried or worn | Pocket, velvet pouch, acrylic capsule, or a case with an engraved nameplate | Ribbon around the neck, or mounted on a display hanger; neck ribbon runs 860–900 mm long by 20–30 mm wide | Clutch back or a magnet back, with magnet diameters from 2 to 20 mm |
| Finish that suits it | Antique gold, antique silver, two-tone, matte black | Antique gold, antique bronze or matte, with deep recesses for contrast | Imitation hard enamel, polished flush with the metal borders |
| Role of enamel | Accent only — branch colors in selected recesses | Branch colors across the recessed field, with the metal carrying the relief | Primary — most of the visible surface is color rather than metal |
| Numbering | Laser-engraved on the edge or reverse; sequential or roster-supplied variable data | Laser-engraved on the reverse field | Rarely numbered |
| Tooling and MOQ | One mold per design, 100 pieces per design | One mold per design, 100 pieces per design | One mold per design, 100 pieces per design |
| Reorder behavior | Mold retrieved from the archive under your unit designation; the batch matches the last one | Same custody rule; ribbon and hanger specs are re-ordered alongside | Same custody rule; the crest artwork is reused so the pin and the coin match |
The practical rule: if it has to survive a pocket and a handshake, buy the coin. If it has to be worn on a parade ground or hung in a shadow box, buy the medal. If it has to be identifiable at a distance every working day, buy the pin — and cut all three from the same approved crest artwork so the set reads as one program rather than three separate purchases.
Diameter × Thickness × Alloy — Hand-Weight Reference Table
Weight is the specification buyers cannot judge from a drawing. The figures below are calculated from alloy density — aluminum 2.7, zinc alloy 6.7, iron 7.8 and brass 8.9 g/cm³ — against a solid disc at each nominal diameter and thickness. Use them to shortlist a combination before you ask for a quote, and to sanity-check any weight a supplier quotes you.
| Diameter | Thickness | Aluminum 2.7 g/cm³ | Zinc Alloy 6.7 g/cm³ | Iron 7.8 g/cm³ | Brass 8.9 g/cm³ | How It Reads in the Hand |
|---|---|---|---|---|---|---|
| 1.5 in (38 mm) | 3 mm | 9 g | 23 g | 27 g | 30 g | Pocket coin — sits in a trouser pocket without pulling the fabric |
| 1.75 in (44 mm) | 3 mm | 12 g | 31 g | 36 g | 41 g | The standard unit coin — noticeable when handed over, comfortable when carried |
| 1.75 in (44 mm) | 4 mm | 16 g | 41 g | 47 g | 54 g | Heavier standard — the thickness buyers pick when the coin is the presentation itself |
| 2 in (50 mm) | 4 mm | 21 g | 53 g | 61 g | 70 g | Presentation weight — substantial enough to be passed around a room |
| 2.5 in (63 mm) | 4 mm | 34 g | 84 g | 97 g | 111 g | Two-hand weight — the point where brass starts to feel like a paperweight |
| 2.5 in (63 mm) | 6 mm | 50 g | 125 g | 146 g | 166 g | Oversized command piece — meant for a case, a desk or a shadow box, not a pocket |
| 3 in (76 mm) | 6 mm | 73 g | 182 g | 212 g | 242 g | Display only. This is why zinc alloy is specified at 3 in and above — brass at this size stops being practical to strike and to carry |
These are solid-disc figures — the theoretical upper bound at that diameter and thickness. A finished coin weighs a little less: 3D relief, cut-outs, an openwork center and an edge chamfer all remove metal, and plating adds almost nothing. Read the table as a ranking tool rather than a shipping weight. The number that matters is the gap between columns — at any given size, brass is roughly a third heavier than zinc alloy, and that is the difference a recipient notices before they have looked at the design.
Edge Treatment Comparison — Reeded, Rope, Cross-Cut, Diamond-Cut, Wave & Plain
The edge is the one surface a recipient touches before they look at the design, and it is the option most coin pages leave out. It also interacts with three other decisions: whether the coin can carry edge lettering, which plating shows it to best effect, and whether the piece needs a capsule. None of the edges below changes the mold fee — the choice is made after the artwork is approved.
| Edge | How It Is Produced | What the Thumb Reads | Pairs Best With | Practical Note |
|---|---|---|---|---|
| Reeded | Parallel ridges rolled or cut around the rim — the profile you feel on a quarter | The instant 'this is a coin' cue; familiar, traditional, authoritative | Antique gold and antique silver on traditional unit coins | The most forgiving edge for concealing minor handling wear, which is why it is the default for pocket-carried coins |
| Rope | A twisted-cord relief cut around the rim | Decorative and maritime; reads as heritage rather than currency | Navy, Coast Guard and maritime commands; anniversary editions | Needs more rim width than reeding, so it suits 1.75 in and above |
| Cross-cut | Grooves cut at opposing angles to form a cross-hatch | Gritty and high-grip; the tactical edge | Matte black and other dark finishes | The recesses hold shade, so the edge reads darker than the face — useful when you want the rim to disappear under stage lighting |
| Diamond-cut | A 45° bevel ground and polished around the perimeter | A bright line of light that travels around the coin as it is turned | Presentation pieces under ceremony lighting; antique gold and two-tone | The bevel is polished rather than protected, so it is the edge most worth pairing with an acrylic capsule |
| Wave | A shallow sinusoidal relief running around the rim | Soft and decorative; catches light unevenly | Commemorative and anniversary editions | Often run against a rope edge on the reverse on two-sided designs |
| Plain / smooth | An unworked rim, lightly polished | Clean, modern, minimal | Any piece carrying laser-engraved edge text | The only practical base for edge lettering or a serial number wrapped around the rim |
| Edge lettering or numbering | Laser engraving wrapped around a curved surface | Text or a number you read by turning the coin over | Unit mottoes, deployment dates, coordinates, sequential numbering | Specify the string and its placement on the drawing; engraving a curved surface is an additional pass, not a mold change |
Variable Data & Numbering — Laser, Stamping, Screen Print and Pad Print Compared
"Can each coin be numbered" is the easy question. The harder one is which method should put the number there, because the four options differ in where they can reach, what they survive, and whether they can carry per-piece data at all. This is the comparison we run when a command sends a roster file.
| Method | Where It Can Go | What It Survives | Data Flexibility | Cost Behaviour |
|---|---|---|---|---|
| Laser engraving | Edge rim, reverse field, or any flat panel on the face; works over plated and antique surfaces | A mark cut into the metal itself — it does not wear off with handling | Sequential runs such as 001 through 500, or variable data straight from a roster file: names, ranks, dates, unit designators, QR and data-matrix codes | One-time data programming per order plus a per-unit pass. The most economical route for a numbered edition, and the only one that handles per-piece data |
| Stamping from the mold | A raised or recessed element of the design, struck with the coin | As durable as the coin — there is no post-process to wear off | Fixed data only: the same date or the same number on every piece in the run | Quoted as a tooling line, because the number is cut into the steel. Worth it when the number is part of the artwork rather than a per-piece identifier |
| Screen print | Flat areas of the face | A surface deposit; acceptable on display pieces, less so on a coin carried loose in a pocket | One design repeated across the run — not practical for per-piece variable data | Priced per color per pass. Suited to a fixed layout repeated on every piece |
| Pad print | Flat or gently curved areas, including small recessed panels a laser cannot reach as cleanly | Similar durability to screen print | Short strings, codes and small logos | Priced per color. The fallback when the only clear panel on the coin is recessed |
| UV printing | Flat faces, holding registration across relief up to 7 mm | A cured full-color layer on the surface | Full color: gradients, photographic detail and imagery alongside numbering | Quoted per pass. The choice when the data itself has to be in color rather than in bare metal |
For a numbered edition, the decision is usually between laser and stamping. Laser if every coin needs its own number. Stamping if the run shares a date and you want it struck rather than engraved. Supply the roster file — Excel or CSV — with the artwork rather than after the sample, so the data is programmed from one source instead of being retyped.
Procurement & Acceptance Documents — What to Request at Quote Stage
Military, police and municipal buyers rarely lose time to production — they lose it to paperwork that was requested too late. Everything in this table is available before you commit budget. Ask at quote stage and the file is complete by the time the purchase order is raised.
| Document or Record | When to Ask for It | What It Should Contain | Why Procurement Needs It |
|---|---|---|---|
| Factory certification copies | With the quote, before budget is committed | BSCI, Disney FAMA, ISO 9001, Reach, RoHS, TUV Rheinland, Sedex and USJ — 8 active certifications, audited annually | Lets the compliance file be built before the purchase order is raised rather than after |
| Line-item quotation | With the quote | Mold fee, unit price, plating, numbering and packaging broken out on separate lines | Institutional purchasing codes each line against its own budget heading; a single lump sum cannot be coded |
| Material and substance declaration | Before the sample is approved | The alloy specified for each component, with Reach and RoHS conformity stated | Required by most government and agency purchasing systems before a supplier can be approved |
| Free design and 3D rendering | Inside 24 hours of the brief | A vector redraw of the supplied insignia, with unlimited revisions, issued as a 3D rendering for approval | Nothing is cut until this is approved, so it is also the record of what was agreed |
| Pre-production sample record | 7–10 days after artwork approval | Photo and video confirmation as standard; a physical sample on request | The reference both sides sign off against before mass production starts |
| Three-stage QC record | At each gate — after casting, after plating and after color filling | Findings at each gate, with sample photographs | Evidence for acceptance, and the basis for any claim raised after delivery |
| Packing list and country of origin | Before shipment | Piece count per carton, packaging type, and origin documentation | Customs clearance and goods-in reconciliation at the receiving office |
| Payment terms confirmation | With the quote | T/T, 30% deposit with 70% balance before shipment; Net 30 or Net 60 for returning customers | Matches the way unit funds and association treasurers release money against a fiscal calendar |
| Mold custody statement | With the first order | Mold cut in mold steel, heat-treated, labeled with your unit designation, archived as your property and never reused for another client | Proves a reorder will match the original batch, and that unit identity is not resold |
Annual Reorder & Mold Archive — New Mold, Amendment, or No Change
Your mold is cut in mold steel, heat-treated for hardness and wear resistance, labeled with your unit designation and held in our archive. It is never used for another client and never shown to one. What is less obvious is which changes on a reorder require new steel, which are a tooling amendment, and which cost nothing at all — resolved below, because it is the question that decides the reorder quote.
| What Changes on the Next Order | Classification | What Happens to the Tooling | What It Means for the Quote |
|---|---|---|---|
| Nothing — same artwork, same size, same year | No tooling change | Mold is retrieved from the archive under your unit designation | Reorder priced without a new mold fee; the new batch matches the last one |
| The year or date only | Tooling amendment | The date element is re-cut into the existing mold steel | Quoted as an amendment rather than a complete new mold — the most common change on an annual program |
| A new or extended serial numbering sequence | No tooling change | Numbering runs after plating as a laser pass | Data programming is re-set; no steel work and no effect on the mold |
| Names, ranks or dates on variable data | No tooling change | Roster file is re-supplied and re-programmed | No steel work; send the updated file with the order, not after it |
| Finish only — antique gold to matte black, for example | No tooling change | Same mold, different plating program | Plating is re-quoted; the mold cost is not repeated |
| Size change — 1.75 in to 2 in, for example | New mold | A new mold is cut; the original stays in the archive | New tooling line, and the original remains available for the old size |
| Outline change — round to shield or crest | New mold | New mold cut to the new silhouette, with the 2 mm minimum wall respected | New tooling line, quoted against the new geometry |
| Added 3D relief or a raised element | Amendment or new mold, depending on depth | The cavity is re-engraved where the change is contained, otherwise re-cut | Quoted after we see the artwork; doubling the relief roughly doubles the mold work |
| Mold released or destroyed | Custody action | Mold shipped to you or destroyed, with documented confirmation | Your property, actioned on your instruction only |
The pattern worth planning around: a date change is an amendment, a size change is a new mold, and a finish or numbering change is neither. If your program reorders every year, fix the diameter and the outline on the first order and let the year be the only thing that moves.
Where a Coin Program Goes Next — Sets, Costs & Adjacent Categories
Once the coin is specified, the next questions are almost always about the pieces around it: what the set costs, how it is packed, and which categories run on the same artwork. These are the pages most unit programs open next.
