The listing, 1964 Silver quarter has ended.
This is a 1964 Washington quarter. It was struck at the Denver Mint and is the last struck in 90% silver! For 168 years, since 1796 when the U.S. Mint began striking quarters, they had been minted in 90% fine silver. In the early 1960s, demand for silver picked up, and a coin shortage developed in the U.S. So 1964 became the final year 90% silver coins were struck. Early Washington quarters are now loved by collectors, they are the last struck in 90% silver!
