Collectible coins, particularly U.S. quarters, often attract numismatists due to their historical and aesthetic value. The 25-cent quarter, specifically the Washington Quarter, features a design of George Washington and has been produced since 1932. The 1987 San Francisco Mint quarters are notable for their "S" mintmark, indicating they were struck in San Francisco, and are often sought after by collectors for their quality and limited mintage. These coins can vary significantly in value based on their condition, rarity, and demand in the market.
