Blank Brass Challenge Coin Laser Engraving Coins Blanks 40 mm with Acrylic Protection Box for DIY Crafts Birthday Travel Commemorative Collection (10pcs Brass)

My go to for fiber laser engraving blanks. Solid brass, easy to engrave and customers love the coins.

These are very nice. Much thicker than others I have bought. Also has a flat polished surface rather than the textured on others. Highly recommended. Cost is higher, but worth it. Used for fiber laser engraving

These coins are solid brass! At first, I thought I might be getting a knockoff claiming to be brass, but after cleaning them up after the fiber engraving, they came out nice and clean. I have a couple of others I made, but they are not appropriate for showing due to the words on them. These are certainly worth the money and feel and look great.

Okay, if you're looking to get some blank brass challenge coins to run through your 60W fiber laser, you're in luck – they're definitely out there in bulk and are a popular material for laser engraving! Brass is a great choice for fiber lasers because they interact well with metals, allowing for detailed and lasting marks, from surface etching to deeper engraving depending on your machine's settings and power. You can find these blank brass coins from various suppliers online, including places that specialize in engraving blanks or even larger marketplaces that connect you directly with manufacturers. When you're looking, keep an eye out for descriptions that specify "solid brass" and mention suitability for laser engraving. A 60W fiber laser should give you plenty of power to get some really nice results on brass, allowing you to create custom challenge coins with intricate designs, text, and logos for whatever projects you have in mind.

Coins were mainly consistent with quality, all having a nice, initial shine to them. The are pretty accurate when it comes to coin size, shape, and stamp. They work well with laser engraving and have nice housings to place the finished coin in. Only issue I ran into was one of the coins had soft, almost dent-like edge to it (more noticeable in real life). For almost paying 3 dollars a coin, I would expect this to not be an occurrence, but overall, good coin.
