Collectible coins, also known as numismatic coins, vary in value based on factors such as rarity, condition, demand, and historical significance. The United States quarter, specifically the Washington Quarter, has been produced since 1932, with the 1970 release being part of a series minted in Philadelphia. Numismatists often seek out specific years, mint marks, and variations, making the 1970 Philadelphia quarter an area of interest for collectors. Collectible quarters can be valued based on their circulation status, such as uncirculated or proof, and their historical context within U.S. coinage.
