United States quarters minted in 1967 did not contain silver. Prior to 1965, circulating quarters were composed of 90% silver and 10% copper. However, due to rising silver prices, the composition was changed to a clad construction, consisting of outer layers of 75% copper and 25% nickel bonded to a core of pure copper. Therefore, the intrinsic metal value of these coins is significantly less than pre-1965 issues.
The shift away from precious metal in coinage was a response to both the increasing cost of silver and the potential for coin shortages. The public began hoarding silver coins due to their bullion value exceeding their face value. This transition period marked a significant change in United States coinage and affected the numismatic value and collectibility of quarters produced in those years.
