Certain United States quarters, specifically those minted in 1964 and earlier, contain 90% silver. These coins, unlike their more modern counterparts, possess intrinsic precious metal value derived from their composition. A notable example is the Washington quarter produced before 1965; these contain approximately 0.18084 troy ounces of silver.
The significance of these coins extends beyond their face value. Their silver content makes them desirable to collectors, investors, and those interested in precious metals. Historically, they represent a period when circulating currency was backed by valuable commodities, offering a tangible link to the past. Furthermore, their inherent metal value can serve as a hedge against economic uncertainty, providing a store of wealth during periods of inflation or currency devaluation.
