If you’ve ever paid attention to coins in daily life, you’ll notice something interesting: most modern currencies are not made from precious metals anymore. Instead, governments rely on durable, affordable base metals that can survive years of circulation.
Take common circulating coins as an example. Many are made from brass, nickel, or zinc-based metals—materials that still carry value, but are far more practical than silver or gold. The U.S. Lincoln Shield cent, for instance, is made primarily of zinc, keeping costs low while maintaining a familiar appearance.
That’s everyday currency.
Challenge coins are a different story.
What Materials Are Challenge Coins Actually Made Of?
When people first see challenge coins, one of the most common questions is:
“If these coins can be gold, silver, black, or antique bronze, are they made from different metals?”
The short answer is: no.
Despite their wide range of colors and finishes, challenge coins are usually made from just a few core materials:
- Iron
- Zinc alloy
- Copper
Those gold, silver, black, or antique finishes you see?
They are plated layers applied on top of the base material, not the material itself.
Quick Guide to Choose the Right Material for your Challenge Coins
| Material | Best For | Design Complexity | Typical Thickness | Estimated Unit Cost* |
|---|---|---|---|---|
| Iron | Simple stamped designs | Low | 1.5–3.0mm | Very low |
| Copper | Antique bronze look, weight | Medium (3D supported) | Usually 3.0mm | $0.70–$0.80 |
| Zinc Alloy | 3D designs, custom edges | High | Fully customizable | $0.40–$0.50 |
*Prices based on 1.5-inch, 3mm challenge coins and may vary by quantity and design.
Iron Challenge Coins
Pure iron is not very common for challenge coins, but it does have its place.
Iron challenge coins are:
- Very affordable
- Heavy and solid
- Best suited for simple stamped designs
Because iron is quite hard, it doesn’t shape easily. That means:
- No complex 3D designs
- No gear edges or custom-cut edges
- Limited detailing
Iron coins are usually made in fixed thicknesses such as 1.5mm, 2.0mm, 2.5mm, or 3.0mm.
In practice, 3mm thickness is the most popular choice to ensure a solid, premium feel.
If your design is clean and straightforward, iron can be a cost-effective option. But once you want more creativity, iron quickly becomes limiting.
Copper Challenge Coins
If you’re aiming for a vintage or antique bronze appearance, copper is a great base material.
Copper challenge coins:
- Naturally suit antique bronze or antique copper finishes
- Can support 3D designs
- Feel heavier and more substantial than zinc alloy
Typical thickness options are similar to iron—most commonly 3mm for a premium feel.
As a real-world reference:
- A 1.5-inch, 3mm thick copper challenge coin
- Unit price usually falls around USD $0.70–$0.80, depending on design and quantity
Copper is often chosen when the goal is weight, texture, and a classic look, rather than highly complex shapes.
Zinc Alloy Challenge Coins
If there’s one material that dominates modern challenge coin production, it’s zinc alloy.
Zinc alloy is popular because it’s:
- Easy to mold and shape
- Ideal for 3D designs
- Perfect for custom edges (gear edge, rope edge, irregular shapes)
- Compatible with almost all plating options, including antique silver and black nickel
Unlike iron or copper, zinc alloy offers much more flexibility:
- Size can be fully customized
- Thickness can be adjusted based on design needs
- Complex details are easier to achieve
For pricing:
- A 1.5-inch, 3mm thick zinc alloy challenge coin
- Typically costs around USD $0.40–$0.50 per piece
That balance of price, design freedom, and finish options is why zinc alloy is the go-to choice for most custom challenge coins.
