The mass of a United States quarter coin composed of 90% silver and 10% copper is a key characteristic distinguishing it from its more modern, clad counterpart. These “silver quarters,” primarily minted before 1965, are prized by collectors and precious metal investors due to their intrinsic silver value. For example, a circulated Washington quarter from 1964 will possess a specific weight reflecting its silver content.
Understanding the specific mass of these coins is important for several reasons. It allows for quick authentication, aiding in the identification of genuine silver quarters versus counterfeit pieces or later, non-silver compositions. Furthermore, knowing this figure is crucial when evaluating the silver content of a group of coins for investment or melt value calculations. The historical context is also significant, as the switch to clad coinage marked a shift in U.S. monetary policy.
