01Zinc alloy · fine detail
Die-Cast
Molten zinc alloy is injected into the mold under pressure, capturing fine lines, small text, and complex shapes at a lower unit weight and cost.
Best for detailed artwork, larger diameters, and larger runs.
CUSTOM CHALLENGE COINS
A coin built to be held.
Born in military units and carried into boardrooms, the challenge coin is a recognition object with real physical presence. Deep 3D relief, diamond-cut edges, and dual-tone plating — two faces and one edge, designed to be handed over and kept.
Weight in the hand.Detail on both faces.A piece worth keeping.
- MOQ 100 pcs per design
- Sample 7–10 working days
- Thickness 3.0–4.5 mm

FrontFrontIdentity side
The primary emblem, unit mark, or logo sits highest in the relief, so the center reads first — in the hand and in photographs. Visual hierarchy is decided on this face.

II · DESIGN & CRAFT
Three surfaces. One object.
A challenge coin is judged from every angle — front face, reverse face, and edge. We plan all three as a single physical object, then choose the finishes that make the relief readable.
Two ways to build the coin.
Before finishes, the manufacturing route is chosen. Both methods hold fine detail — they differ in weight, relief depth, and how the finished coin feels in the hand.
02Brass / copper · deeper relief
Die-Struck
A metal blank is struck between dies under high pressure, producing a denser, heavier coin with deeper relief and a crisper edge.
Best for maximum weight, deep 3D relief, and premium feel.
Choose the finishes.
Five decisions shape how the coin reads — relief depth, edge treatment, plating contrast, color fill, and special effects. Review each option before committing to a specification.
01 / 05OPTION 01
Depth first3D Relief
The central emblem is raised above the field so it reads as the visual anchor and catches light on its own.
- Construction
- Artwork is separated into relief layers — raised emblem, recessed field, text, and edge details — before the mold is cut.
- Why choose it
- Depth survives photography and handling; the coin reads as a physical object rather than a printed token.
- Considerations
- Deeper relief needs a thicker coin and finer metal flow at the edges; extremely fine detail may need to move to the reverse.
III · APPLICATIONS
Where coins carry meaning.
From unit identity to fan merchandise — a challenge coin works best when it stands for something the owner wants to carry, hand over, or keep.
01
Military & Units
Unit coins, deployment coins, commander's coins, and branch anniversaries — the tradition the format was born in.
02
Law Enforcement & First Responders
Police, fire, and EMS coins for recognition, promotion, memorials, and academy graduation.
03
Corporate Recognition
Employee milestones, executive gifts, sales awards, and brand-identity coins that carry a company mark into the field.
04
Commemorative Editions
Anniversaries, retirements, and memorial pieces — often serial-numbered for a limited run.
05
Brand & Fan Merchandise
Collector coins for sports teams, esports organizations, fan communities, and pop-culture releases.
06
Events & Challenges
Event coins, fundraiser pieces, and membership coins that mark a shared experience.
IV · PRODUCTION & QUALITY
From artwork to a coin with real depth.
A controlled six-step process — from your first artwork to the finished, inspected coin. The unplated blank is checked for relief before plating, because depth cannot be fixed later.
Design
We review your artwork, dimensions, details, colors, and finishing requirements.
Mold
A custom mold is created from the approved design.
Forming
Die-casting or stamping creates the metal body and relief details.
Plating
The product receives the selected gold, silver, bronze, antique, or other metal finish.
Finishing & Inspection
Enamel, printing, polishing, final detailing, and quality checks are completed.
Packing
Finished products are packed according to project requirements and prepared for shipment.
BEFORE DISPATCH
Confirm the details that matter.
- Approved front and reverse artwork
- Relief depth and edge profile sample
- Plating and enamel color match
- Serial numbering accuracy
- Packaging and quantity specification

Frequently asked questions.
Still have a question? Send us your artwork and project details and we'll help you work it out.
What is the minimum order quantity?
Our standard MOQ is 100 pieces per design. For test orders, we can accept 50 pieces with a small surcharge.
How long does sampling take?
Sampling normally takes 7–10 working days after artwork approval, depending on design complexity and finishing requirements.
Can both sides be fully custom-designed?
Yes. Front and reverse are treated as one system. Each side can carry its own relief, enamel fill, engraved text, and plating treatment.
What edge treatments are available?
Common options include diamond cut (reeded), smooth polished, hand-finished antique, and engraved edges with serial numbers or unit text.
What is the difference between soft and hard enamel?
Soft enamel leaves the raised metal lines visible and reads brighter and sportier. Hard enamel is ground flush and polished for a smooth, premium surface. Offset printing is also available for gradients and fine detail.
Can we add serial numbers or individual engraving?
Yes. Serial numbers, names, and unique text can be engraved on the edge or reverse face — either as part of the mold, or as post-production laser engraving.
What thickness is best for a challenge coin?
Most challenge coins fall between 3.0 mm and 4.5 mm. The right thickness depends on how much physical presence you want in the hand — thicker coins feel more substantial, but weigh more per unit.
What packaging options are available?
Standard packing is individual OPP bags. Velvet pouches, coin capsules, and presentation boxes are available for retail, gift, and commemorative programs.
