Coin Silver refers to a type of silver alloy that was commonly used in the United States during the 19th century. It typically consists of 90% silver and 10% copper, making it a durable material for crafting items like coins, utensils, and jewelry. The term originated because the silver used in these items was often derived from melted-down coins. The use of Coin Silver declined with the introduction of standardized silverware and the rise of sterling silver, which contains 92.5% silver. Today, Coin Silver is valued by collectors and antique enthusiasts for its historical significance and unique craftsmanship.
