10 Pcs Blank Challenge Coin, Engraving Blanks Coins, Solid Brass/Zinc Alloy Silver Plated 40mm Diameter with Acrylic Protection Box Pattern for DIY Crafts Engraving

cut these on my fiber laser to make custom challenge coins great quality buy these

Best to go with a solid material vs coated according to my mentor. Did come with cases around each coin and a case to hold them all in.

Great for engraving, love the included cases

I used OMTech marking spray and a 2W infrared laser to mark these coins. Turned out beautifully! I do recommend that you apply clear coat paint spray after marking.These coins are very high quality, and the cases are very durable.Highly recommend.

My son bought these, the surface was smooth and engraved well on my xTool F1. I wanted some for myself, so had him send me the link from the product he purchased.Mine arrived with a textured finish on the face. These also engraved well on my F1, so no complaints about that, just the inconsistency of the finish from batch to batch.

I got these to make challenge coins for some friends of mine. They are easy to laser with a fiber laser. They get black once you get through the gold layer so they are not solid brass but an alloy of some kind. They came well packaged. I've ordered several sets of these and they all worked well. I like the sawtooth type edge of these coins so they look like coins.

These work perfect for what we wanted to use them for. (With our laser engraver) my only complaint is I don't know what I can do to protect the design after I engrave it to keep my design (more my fault then the product itself)

Only engravable with a fiber laser
