Review: Good material - Good material, good engravings coming out of these
Review: Heavy, protected/encapsulated, easy to engrave with a great starting finish for lasers. - These were my 3rd attempt at finding a good quality brass coin for engraving with LaserPecker 5 engraver. They all came in individual capsules and in great shape. I felt the finish was perfect for engraving, yet easy to polish afterwards. Coin are heavy and feel very high quality compared to the 2mm and 2.5mm ones I purchased prior. I did find that depending on the type of engraving (embossed/3D vs. 2D photo, using a black matte marker first, then wiping off afterwards, resulted in a much bolder/deep engraving. Setting are still tricky with the LP5, however, these coins were exactly what I needed.

### ⭐⭐⭐⭐⭐ Worked great, good quality
*by T***M on February 19, 2025*

I have the F1 Ultra from xtool. Took a few times to get the setting dialed in and engraved nicely on both sides. I didnt use a depth map rather a png from adobe illustrator with 3 different grey scale. I could have blurred a bit but I like the sharp edges from my lettering. the emboss was text and objects the grey scale was the depth and settings was 300dpi, 3000 speed, with 120 layers at 100 power and freq 30.
