Collectible coins include various types such as cents (1c) and half dollars (50c), often sought after by numismatists. Proof sets, particularly from the United States, contain coins that have been specially processed to achieve a high-quality finish, making them desirable for collectors. In 1940, the Philadelphia Mint produced various coinage, including notable examples in these Proof sets. Collectors often focus on aspects such as rarity, condition, mint marks, and historical significance when assessing the value of these coins.
