When preparing the coin surface for carving, some artists like to go through various polishing grits progressively, but in case you don't have patience, or you think you can do a good job faster, you can consider getting a hand rotary tool, such as the Dremel or CRATEX CTX-800 Rotary Handpiece and some abrasive mounted points.
CRATEX abrasives are made of silicon carbide, bonded with premium quality synthetic rubber. They are the perfect tools for light grinding and metal finishing operations, such as smoothing, cleaning, smoothing and polishing and they will fit your Dremel rotary tools perfectly.
They come in four different grit types: coarse, medium, fine and extra-fine. The grit grade that you'll use will the depend on the type of the nickel metal and the amount of metal that you would like to remove. For smoothing down coin surfaces, use coarse to fine grits and for removing carving scratches use extra fine grits and smallest diameters.
