I am making rings, earrings, bangle bracelets and cuff bracelets from coins. These are all hand made in my shop. I use primarily silver coins using ninety percent silver coins and other coins with other silver contents down to fifty percent. I also use some coins that are .999 silver content known as fine silver. I use coins like current us quarters, dimes, and half dollars which are made of 91.67% copper - 8.33% nickel, some copper coins and others. Some coins are made by private mints and are not currency coins.
