There may or may not be any coins destroyed for the making of this pretty item. "Coin silver" is a term used to define the purity of silver in an object, not necessarily the origin of that silver.
Quote:Coin silver is a standardized alloy of silver that has been used in the United States since 1792. Items that are stamped as coin silver were guaranteed to have the same purity as American silver coins.
Original Definition
Prior to 1906 there was no law defining coin silver, but it was an unofficial category used by manufacturers of silver products to assure their consumers. Often it meant that the silver in the products came from melted-down coins, but these coins could also have been from other countries, or of dubious purity.
Old Coin Silver
Because coin silver had no legal definition, items that were marked as coin silver could vary from below 75-percent to above 95-percent pure. Most coin silver, however, was between 89.2-percent and 93-percent pure (which was the range used for silver coins in the U.S.).
Legal Coin Silver
In 1906 the National Stamping Act defined coin silver as being at least 90-percent pure. Everything made after 1906 and stamped with COIN must meet this purity standard.
Marks
As well as COIN, coin silver may be stamped with PURE COIN, DOLLAR, STANDARD, or PREMIUM.
