The 1964 Washington Quarter is a notable collectible coin from the United States, specifically minted in Philadelphia. As part of the 25-cent denomination, it features the iconic profile of George Washington on the obverse and an eagle with a shield on the reverse. This coin is particularly significant as it marks the last year the quarter was produced with 90% silver content, making it highly sought after by collectors. The 1964 Philadelphia Mint version does not have a mint mark, distinguishing it from quarters minted in other locations.
