@pleiades357 Ideally I would use a metal punch in a wood block. This will give the best dome without damaging the designs on the coin. A wood punch on a wood block will work but it will harder to form. I would avoid using a steel punch on a steel block. It forms great but you could damage the designs.
@nrred From Mark Nelson: Really the best gauge to do it with is the gauge that fits the design and function of the jewelry the best. It works with thick metal and thin. However, that being said, the thicker and the thinner the metal is the harder it will be to form. 16 gauge is about as thick as I like to go and I sometimes have to anneal it 1/2 way through, depending on how deep I need it to be. And 28 gauge is as thin as I like to go, usually when I need to dap a really small piece.
strange i was trained to go from outer side in concentric circles inward to keep from cracks that can occur even when annealed plus ... to keep memory marks down if its engraved on the other side
I can't wait to try this!

Rio Grande has been my favorite supply source since... long ago. I've always wished I lived near by. This is the next best thing ;-)
