Coin silver is a term used to refer to the alloy that resulted when pre-1965 US silver coins were melted down to reuse in jewelry making. Early Native American craftsman made jewelry directly from the coins, heating the coins in a fire pit or forge and hammering them into shape.The Naja Symbol - The naja, (an inverted crescent) has represented a variety of meanings throughout ancient history. Used as a symbol for the Phoenician goddess of fertility, and for the Spanish Moors as protection from the "evil eye". The Navajo adopted the symbol from the Spanish, originally using it as decoration for their horses headstalls. Later it became the crowning achievement of their squash blossom necklaces, as no squash blossom is complete with out it. The Navajo claim there is no precise symbolic significance of the naja, however, it is prevalent in their culture and held in high esteem.
