Collectible coins encompass various types, including numismatic coins, bullion coins, and commemorative coins, each with distinct values based on rarity, demand, and condition. The United States quarter, specifically the Washington Quarter series, began in 1932 and includes various mintmarks, with coins minted in San Francisco often being sought after due to their limited production. The 1973 San Francisco Mint Washington Quarter features a unique design and is part of the bicentennial celebration, which appeals to collectors focusing on both date and mintmark varieties.
