Custom Challenge Coins | Hard Enamel Border, Diamond Edge
$2.95
The coin in our photo is only half the tool: a gold-plated round with a glossy hard-enamel border legend, a sculpted bare-metal figure over a striped centre field, and a faceted diamond-cut edge – side one, with the reverse waiting for your issue line, motto and names. We design both faces on one approval sheet so relief, border width and plating stops align across the die set. Enamel cost rungs go from plain struck metal to soft-filled recesses to the polished-flush border shown here, and edge style switches between reorders without recutting artwork. MOQ 100 pcs per design, proof coins in 3-5 days, bulk 7-15 days after artwork approval.
Most buyers order their first challenge coin backwards: they perfect one face, leave the reverse blank, then discover a month before delivery that the back is where names, dates and mottos were supposed to live. This guide works from the coin in the photo – a gold-plated round with a glossy hard-enamel border ring, a sculpted central relief over a flag-stripe field, and a faceted diamond-cut edge – and treats it as exactly what it is: side one of a two-sided tool. Every custom challenge coins commemorative decision you make gets cheaper and cleaner when the obverse and reverse are designed together against one die set.

Side One Is the Poster, Side Two Is the Ledger
The photographed face does what an obverse should: one big readable idea. A five-name legend circles a blue enamel border separated by struck stars, and a sculpted figure in bare polished metal rises over a striped field in the centre. No small text, no clutter – the design survives being tossed on a desk or held up in a photo. The reverse is the working side, and this sample doesn’t show it, which is the point: on your coin, the back carries the issue year, chapter or roster line, a motto zone, and a smooth field for numbering. We layout both faces on the same mock-up sheet so relief heights, border width and plating stop align across the two tools, instead of two separate design files that argue with each other at the die shop.
Hard Enamel Border: Why the Colour Here Is Flat
Run a fingernail over the blue ring of the sample and it would travel level from metal star to metal star. That is hard enamel: colour paste fills each cloison cell, overfills slightly, then the coin is ground and polished until fill and separator sit on one plane with a glass gloss. It costs a second pass beyond soft enamel, but for a border ring that reads at arm’s length it holds pigment crisp for years. The recessed alternative – soft enamel with polished metal proud of the colour – suits centre fields where shadow adds depth. Many of our repeat orders mix both: hard ring outside, soft centre inside, quoted as one build rather than two surprises.
The Faceted Edge Is a Tooling Choice, Not Decoration
Zoom the rim: instead of the usual smooth or rolled edge, it is cut into triangular facets that glitter as the coin turns. A diamond-cut edge is cut on the edge lathe after striking, before plating, and it hides handling marks better than a plain rim while giving the coin tactile identity in a pocket. Edge options we quote on the same blank: rolled, knurled, plain, saw-tooth, and this faceted cut. Because edge work happens off the main die, switching edge styles between orders does not recut your artwork – useful when a client re-issues a coin annually and wants the year told through the edge, not a new obverse.
The Entry Ladder: What the Same Die Can Cost
The sculpted central figure shows one build level; a budget entry coin trims to flat-struck relief with no colour fill at all, and every rung between is a line on the quotation, not a new product. Configure the ladder to your quantity plan.
- Blank and base: zinc alloy or iron struck blank (brass or copper on request, quoted per artwork)
- Plating per face: gold as photographed, plus nickel, antique nickel, copper, black nickel variants across the same die
- Colour rung A: no enamel, polished-or-antique struck metal only – the entry price point
- Colour rung B: soft enamel centre or border, raised metal separators as cloisons
- Colour rung C: hard enamel polished-flush fields as shown on the sample ring
- Sculpted or epoxy upgrades for centre figures quoted against the artwork, one piece at a time
- Edge: rolled, knurled, plain or the faceted diamond cut seen here
- Reverse add-ons: smooth field for names, issue line, or numbering after plating
- Diameter normally 1″–2″; a 3″ coin is quoted when the design needs the extra field, and spin or duomed variants argue a different page’s case

Order Flow: Mock-up, Proof Coin, Then Both Tools at Once
Send one artwork sheet – or two, if obverse and reverse are separate files – and the free digital mock-up returns both faces side by side within two working days, flagging clashes like a border legend too long for the ring or a reverse motto landing under the edge cut. Physical proof coins follow in 3-5 days, struck and plated exactly as the bulk order will be. Because both dies are machined from the same approved sheet, nothing on the back arrives unexamined. Bulk then completes 7-15 days after artwork approval, and a reissue two years from now re-uses the tooling unless the artwork itself changes.
Carton Plan and Worldwide Freight

Coins ship loose in poly bags by count inside corrugated export cartons, palletised on request; individual coin stands or gift boxes are a separate line item, not assumed. Routing runs by sea for stock orders, air or express via DHL, UPS, FedEx and TNT for deadline runs, and FBA pick, pack and labelling prep is available when your coins retail through Amazon fulfilment. Components individually poly bagged keeps hard-enamel faces from chipping against each other in transit.
Buyer Questions About Two-Sided Coin Builds

Can we reorder the same coin next season?
Does the diamond-cut edge wear through the plating?
What artwork format works best for both faces?
Coins, Medals and Pins: the Rest of the Line
If the reverse of your project is actually recognition hardware rather than coin stock, our medal pages separate the jobs cleanly: custom event medals for ceremony podiums on ribbon, custom race medals for enamel finisher runs, and recognition award medals for tiered shields. Stay inside coin country through the coins category, the full metal crafts range, or skip the browsing and send a two-face brief to the request quote desk.
One sheet, two faces, one approval – that is the whole method. Send us the artwork you already have, blank or cluttered, and the mock-up will show what the die shop would actually cut from it.
