Collectible coins include a variety of types, such as Proof Sets, which are specially minted coins with a high-quality finish intended for collectors. In the context of the United States, coins like the 1 cent (1c) and 50 cent (50c) pieces from various years can be part of these sets. The 1942 Proof Set, produced by the Philadelphia Mint, included coins such as the Lincoln penny, Jefferson nickel, Washington quarter, and Franklin half dollar. These coins are sought after for their condition, rarity, and historical significance.
