Where to Buy Challenge Coin Blanks in 2026: Comparing the Best Suppliers for Laser Engraving


If you've recently purchased a fiber laser, one of the first questions you'll probably ask is:


"Where can I buy high-quality challenge coin blanks?"

It's a question that comes up repeatedly in laser engraving communities, especially among users of Fiber Lasers, xTool F1 Ultra, OMTech, ComMarker, and other engraving machines. Discussions on Reddit frequently recommend suppliers such as Swissbui, Umburry, Heavy Metal Blanks, Amazon, AliExpress, Etsy, and several specialty engraving stores.

The right supplier depends on what matters most to you—price, material quality, edge finish, shipping speed, customization options, or available sizes.

Here's a comparison of some of the most popular sources.


Best for: Premium stainless steel, brass, copper, and anodized aluminum challenge coin blanks with decorative edge options.

ABBECIAO specializes in metal stamping and laser engraving blanks. Unlike many general marketplaces, our collection focuses on blanks made specifically for engraving and custom coin making.


Highlights include:

  • Heavy-duty 3mm (1/8") thickness

  • 304 stainless steel, solid brass, solid copper, and anodized aluminum

  • Smooth, faceted, reeded, diamond-knurled, and grooved edge styles

  • Multiple diameters from 25mm to 50mm

  • Individually protected packaging to reduce scratches

  • Retail packs and bulk quantity discounts

  • Custom sizes and OEM manufacturing available


Whether you're creating military challenge coins, golf ball markers, company awards, or collectible commemorative coins, ABBECIAO offers blanks designed for both hobbyists and professional engraving businesses.


Swissbui is one of the most frequently recommended suppliers in laser engraving communities. Reddit users often mention the company for its broad selection of specialty materials and decorative coin styles. It also offers premium materials such as titanium and Damascus options that appeal to experienced engravers.

Best for:

  • Specialty metals

  • Premium finishes

  • Small business engraving shops


Umburry offers a large selection of anodized aluminum blanks and decorative engraving products.

Many engravers appreciate their expanding catalog, particularly for colorful anodized products that work well with diode and fiber lasers.

Best for:

  • Colored aluminum

  • Creative engraving projects

  • Small production runs


Amazon remains one of the easiest places to purchase challenge coin blanks when fast delivery is the priority.

However, several Reddit users mention that product quality can vary depending on the seller, especially with brass blanks where material consistency isn't always guaranteed.

Best for:

  • Fast shipping

  • Small orders

  • Beginners


5. Etsy

Etsy is a popular option for buyers looking for handmade, small-batch, or customizable challenge coin blanks.

Because Etsy is a marketplace made up of individual sellers, the quality, material selection, and consistency can vary widely from shop to shop. Some sellers offer unique decorative blanks, custom sizes, or personalized engraving services, while others focus on hobby-level products rather than industrial-grade blanks.

Best for:

  • Handmade or small-batch blanks

  • Custom or personalized orders

  • Unique designs and niche products

  • Buyers who want to support independent makers


AliExpress offers some of the lowest prices available, especially for larger quantities.

Community feedback suggests that quality is generally comparable to lower-priced marketplace products, although shipping times may be considerably longer than domestic suppliers.

Best for:

  • Bulk purchasing

  • Budget-conscious buyers


What Should You Look for in a Challenge Coin Blank?

Price is important, but experienced engravers usually evaluate several other factors before choosing a supplier.


Material

Choose solid brass, stainless steel, copper, or anodized aluminum depending on your engraving method and desired finish.


Thickness

A 3mm (1/8") blank provides a substantial feel and is the most popular choice for custom challenge coins.


Edge Style

Decorative edges can dramatically improve the finished appearance.

Popular styles include:

  • Smooth Edge

  • Reeded Edge

  • Faceted Edge

  • Diamond Knurled Edge

  • Groove Edge


Surface Finish

A smooth, polished surface helps produce cleaner laser engraving and reduces post-processing.


Protective Packaging


Coins that arrive scratched require extra polishing before engraving. Individually packaged blanks help minimize damage during shipping.
