Collectible coins, especially those from the United States, include various denominations, one prominent type being the quarter. The Washington Quarter, first issued in 1932 to commemorate George Washington's 200th birthday, features his portrait and has become a key collectible. The 1948 Washington Quarter minted in Philadelphia is particularly sought after by collectors due to its lower mintage and historical significance. Collectors often seek to acquire coins in various grades, with higher-quality examples fetching premium prices.
