Collectible coins, particularly those from the United States, encompass a variety of denominations such as 1 cent (penny) to 50 cents (half dollar). Proof sets, which are specially minted coins that showcase a higher quality finish, were produced by the U.S. Mint starting in the 1930s. The 1954 Proof Set from Philadelphia is notable for containing a selection of coins including the Lincoln penny, Jefferson nickel, Roosevelt dime, Washington quarter, and Franklin half dollar. These sets are highly sought after by collectors due to their limited production and exceptional craftsmanship.
