what are the component elements for sterling silver
Sterling silver Fine silver, for example 99.9% pure silver, is relatively soft, so silver is usually alloyed with copper to increase its hardness and strength. Sterling silver is prone to tarnishing[1][2], and metals other than copper can be used in alloys to reduce tarnishing, as well as casting porosity and firescale. Such metals include germanium, zinc, platinum, silicon, and boron. Recent examples of alloys using these metals include Argentium, Sterlium, Sterilite, and Silvadium.[3]
Silver standard Silver certificates continued to be issued until late 1963, when the $1 Federal Reserve Note was released into circulation. For several years, existing silver certificates could be redeemed for silver, but this practice was halted on June 24, 1968.
