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. ## Features - Size Information: Commarker Copper blank Coins :approximately 40 mm/ 1.57 inch in diameter and 3mm/ 0.12 inch in thick.
