History of 1970 S Washington Quarter

The Washington Quarter, first minted in 1932, replaced the Standing Liberty Quarter to commemorate the 200th anniversary of George Washington's birth. Originally composed of 90% silver, its composition changed to a copper-nickel clad in 1965 due to rising silver prices. The 'S' mint mark indicates it was minted in San Francisco, typically for proof sets during this era, making it a collectible item for its condition and proof status.
