Buy Coin Silver from Surepure Chemetals

Coin Silver is an alloy nominally consisting of 90% silver and 10% copper.
Pure silver is too soft to be used for some applications. Coin silver maintains some of the look and ductility of pure silver while adding the hardness necessary for certain applications, such as machined screws.
