ブランク 真鍮 チャレンジコイン レーザー彫刻 カスタム コイン ブランク 40mm アクリル保護ボックス付き DIY クラフト 誕生日 旅行 記念コレクション (真鍮10個)

I bought these thinking, “Cool, some blanks to mess around with.” What I got instead: Crisp, beautiful engravings Professional-looking results An unhealthy level of confidence These are solid brass 40mm coins, about 3mm thick, which is perfect for laser engraving and gives you that satisfying, clean finish every time First attempt: Loaded one into the laser Hit start Expected “meh” What I got: Sharp lines Deep engraving Me staring at it like “did I just become good at this??” The surface is smooth and consistent, so your designs actually come out looking like: You know what you’re doing You planned it You didn’t just hit “run” and hope Also comes with individual acrylic cases, which makes each coin feel like: A collector’s item A trophy Something way more important than it probably is Unexpected side effects: I now refer to my projects as “custom pieces” Mild urge to engrave everything in my house Considering starting a side business after 2 successful coins Things I’ve engraved so far: Logos Random quotes One coin just to see if I could (I could) Final verdict: If you have a laser engraver and want to feel like a straight-up engraving boss, these are perfect. Buy them… but be prepared to become way too confident way too fast.

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.

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.

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
