Soft enamel and hard enamel are the two most common ways color goes into a challenge coin. They look different, feel different, cost different, and serve different purposes. This guide walks through the exact differences so you can pick the right one for your project.
THE 30-SECOND ANSWER
Soft enamel is the workhorse. Colored enamel fills the recessed areas; the metal lines remain raised; you can feel the design with your thumb. Affordable, durable, the standard look most people picture when they think "challenge coin." Right answer for most unit coins, deployment commemoratives, event giveaways, and budget-conscious orders.
Hard enamel is the premium. Colored enamel is filled, fired, then polished flat — color and metal sit flush in a smooth, jewelry-grade surface. More refined look, slightly higher cost, more durable to wear. Right answer for command coins, retirement pieces, change-of-command gifts, executive gifts, and any piece where the finish needs to read as premium.
HOW THEY'RE MADE
Both start the same way: a steel die is cut with the coin design, then metal blanks (typically zinc alloy or brass) are pressed under tens of tons of force to transfer the design into the coin. What's different is what happens next.
Soft enamel process: after striking, colored enamel is poured into the recessed (sunken) areas of the design. The enamel is cured but not polished flat — it stays slightly below the surface of the raised metal lines. The coin is then plated (gold, silver, bronze, etc.) and finished. The result is a coin where you can run your finger across the design and feel the metal lines standing above the colored fills.
Hard enamel process: after striking, the enamel is filled in multiple layers up to the top of the metal lines, then fired at high temperature to harden the enamel. The coin is then polished smooth so the enamel and the raised metal sit flush at the same level. The result is a smooth, gem-like surface where the color appears to be set into the metal rather than poured beneath it.
HOW THEY LOOK
Soft enamel reads with depth and shadow. The metal lines catch light at one angle; the colored recesses fall into shadow at another. You can tell at a glance that the colors are recessed. The texture is visible at arm's length and tactile when you hold the coin. This is the look most people instantly recognize as a "real" challenge coin — it's what military unit coins have looked like for decades.
Hard enamel reads smooth and refined. Without the shadow contrast of recessed color, the design reads more like a printed image set into metal — flat, bright, even. The polished surface catches light differently than soft enamel (more like a piece of jewelry, less like a struck coin). Hard enamel coins photograph better because the surface is even and the colors are saturated; they look more like product photography and less like field-carry equipment.
HOW THEY FEEL
Soft enamel has texture. Run your finger across the design and you feel the metal lines, the recessed color areas, the rope cut edge. The coin's three-dimensional structure is something you can feel, not just see. This is part of why soft enamel coins survive years of pocket carry well — the tactile detail is part of the appeal, and minor wear actually enhances the antique character over time.
Hard enamel is smooth. The polished surface feels like glass — no metal-line texture, no recessed color areas, just one continuous flat plane across the face. Some people prefer this (it reads as premium and "fancy"); others find it less satisfying than the textured soft-enamel feel.
WHAT THEY COST
Hard enamel costs more than the equivalent soft enamel coin — the extra firing time, additional enamel material, and post- polishing labor all add to the per-piece price. For most projects, the difference is meaningful enough to think about but small enough that quality of finish should drive the decision, not price.

WHICH ONE FOR YOUR PROJECT
Pick soft enamel for:
- · Standard unit identifier coins (the everyday coin)
- · Deployment commemoratives, especially at higher quantities
- · Event and corporate giveaway coins where unit cost matters
- · Coins where the textured, traditional look is the goal
- · Field-carry coins that will see real pocket wear
- · Any project where the budget needs to stretch
Pick hard enamel for:
- · Command coins (CO, CMC, Chief personal pieces)
- · Retirement and change-of-command gifts
- · Executive gifts and VIP recognition pieces
- · Coins that need to photograph well for press or marketing
- · Any project where the finish matters as much as the message
- · Coins meant to live on a desk or in display rather than pocket
DESIGN YOUR COIN ONLINE
Use the free online challenge coin designer to sketch your concept. The designer's preview renders both finishes similarly (the visual difference is subtle), but you'll specify soft or hard enamel in the project details when you submit. We send a refined production proof inside 24 hours that shows the finish accurately. See more on every customization option or read about 3D mold construction for designs with dimensional relief.
