Washington Quarter

1932–1964 (90% silver era)

Introduced in 1932 to mark the bicentennial of George Washington's birth, the Washington quarter was meant as a one-year commemorative before becoming a permanent regular-issue design. It was struck in 90% silver through 1964, when rising silver prices forced the Mint to switch to copper-nickel clad -- this guide covers that classic silver era, where the real key dates and doubled-die varieties live.
