Una estafa
El producto no es cobre auténtico como indica en la descripción. De hecho, en el propio texto del anuncio aparece una contradicción: primero dice “cobre auténtico”, pero unas líneas más abajo afirma que “estas monedas están hechas de latón puro”. Esto explica por qué no se comportan como cobre real: no se pueden grabar igual, no oscurecen, y la dureza es mucho mayor. Probado con una máquina láser de alta potencia (1064 nm), el cobre puro se marca enseguida, pero estas monedas apenas reaccionan porque no son de cobre. Son monedas de latón con un baño/tinte color cobre, no cobre macizo. Si buscas cobre auténtico para grabado o para trabajos artesanales, este producto no es adecuado

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.
