Coin Silver

Coin Silver
The alloy of silver favored for currency, though no international standard was ever adopted. Varies from as much as ninety to as little as seventy-five percent silver with the rest added copper or some other metal for hardness. There is a perception that silver made by melting coins is somehow more desirable than silver from other sources. Since sterling is ninety-two point five per cent it is pretty hard to tell one from another. Mostly used in Navajo jewelry. Except in cast pieces, Zuni silver is so minimal it hardly would matter if the collector could tell the difference.
