The composition of United States quarters changed significantly in 1965. Prior to this year, these coins were minted with a 90% silver content, contributing to their intrinsic value and collectibility. These earlier coins are often referred to as “silver quarters” due to this precious metal component.
The alteration in the metal composition was primarily driven by the escalating price of silver. As silver prices rose, the cost to produce 90% silver quarters approached, and at times exceeded, their face value. Maintaining the silver content would have led to coin hoarding and a potential shortage of circulating currency. The switch to a clad composition of copper and nickel alleviated this concern and stabilized the monetary system.
