Collectible coins, such as the United States quarter, are often sought after by numismatists. The Washington Quarter, first minted in 1932, features the profile of George Washington and is commonly made from a copper-nickel composition. The 1978 Philadelphia mint edition of the quarter is part of a series that includes various mint marks, with the Philadelphia mint being unmarked. Collectors often focus on factors such as condition, rarity, and historical significance when evaluating the value of these coins.
