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

These were surprisingly good for the price. Quality of the finish across the whole batch was excellent. I make tokens and challenge coins for promotional materials for businesses and these have been working well with my IR laser for 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.

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

Purchased a Laser cutter. Used these to make challenge coins for friends. Lots of fun and they came out fantastic

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.

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.

Well packaged coins as they come in both a transparent coin holder as well as a little ziploc style baggie. Out of the 90 coins I bought, I can only remember seeing one that had any noticeable scratches on the face of the coin but it didn't matter given the image I was engraving on the coin. They engraved well with my OMTech Fiber laser and everyone liked getting them as a gift. Compared to the pricing on Etsy for a similar offering (which I used in the past), these are a better buy. Will definitely buy these again.

The coins themselves are great. They engrave easily. They have weight and are definitely solid brass. The cases suck. They are hard to open but fit well. If you drop them they will break every time. I didn’t buy these for the display cases but if I had I would be not happy.

Muy muy recomendables, si son de laton, he comprado otras y solo tienen el baño pero por dentro es acero, si las super recomiendo.
