The composition of United States quarters changed significantly over time. Historically, quarters were made of a silver alloy, lending them intrinsic metal value. Specifically, pre-1965 quarters in the United States contained 90% silver and 10% copper. These coins are often sought after by collectors and investors due to their precious metal content.
The value of these older coins stems from their silver content rather than their face value. This precious metal aspect provides a hedge against inflation and economic uncertainty. The historical significance of these coins also adds to their appeal. Their scarcity increases as they are melted down or held by collectors, further influencing their market worth.
