Collectible coins, specifically the Washington Quarter, are a series of coins featuring George Washington and have been minted since 1932. The 25-cent coin, commonly known as the quarter, has several variations, including those produced at the San Francisco Mint, which are often sought after by collectors for their quality and limited mintage. The 1994 San Francisco quarter is part of the series and may feature a "S" mint mark, indicating it was struck at the San Francisco facility, making it a notable example for collectors of U.S. coinage.
