Collectible coins from the United States include various denominations and types, with the 25-cent quarter being a prominent example. The Washington Quarter, introduced in 1932 to honor George Washington, features his portrait on the obverse and various designs on the reverse. The 1968 Denver mint marks a specific year and mint location, which can affect the coin's rarity and value in the collectible market. Collectors often seek quarters based on factors such as condition, mint mark, and historical significance.
