A United States twenty-five cent piece produced in 1965 and composed of 90% silver and 10% copper is a notable numismatic item. These coins represent a shift in U.S. coinage composition, as prior to 1965, circulating quarters were primarily made of silver. This particular issue marks a key transition point.
The historical importance of these silver quarters lies in their intrinsic metal value. As silver prices fluctuate, the melt value of these coins often exceeds their face value, making them attractive to collectors and investors. Furthermore, they serve as a tangible reminder of a bygone era of silver coinage, predating the current clad composition used in modern quarters.
