These octogenarian World War II era silver Washington quarters feature exceptional luster and no wear — and as a testament to their first-rate quality are certified MS-63. These 1942 San Francisco specimens were struck at a time when America was knee-deep in the war effort. Just 19.3 million 90% silver quarters were produced by the branch mint that year, which was five times less than Philadelphia's output. While it may seem like a substantial figure, in present times just one year of the modern commemorative quarter series produces mintage numbers many times that! Grade certification by PCGS or NGC.
