  • Laser on Metal (coins)?

    This might be an absurd question. I have the 2 watt laser with the Piranha and have not used it much yet. In the past year I've been learning the art of engraving, mostly within the little known field of coin carving (hobo nickels). Was just thinking it would solve a lot of image transfer issues if I could lightly etch an outline onto a coin. I would go ahead and just try it, but not even sure if that could damage the laser module. Or perhaps there's something I could coat the coin with and engrave into that? Any idea?
