Collectible coins in the United States include a variety of denominations, ranging from 1 cent (1c) to 50 cents (50c) and beyond. Proof sets, which are specially minted coins known for their fine quality and reflective surfaces, have been produced annually, including in 1952. The Philadelphia Mint is notable for its role in producing these coins, often marked with the "P" mintmark. Collectors seek these items for their aesthetic appeal, historical significance, and potential investment value.
