Collectible coins often include various types such as proof sets, which are specially minted to showcase high detail and mirror-like surfaces, attracting numismatists. The United States Mint produced proof sets, including the 1983 San Francisco Mint Issue, which features coins with enhanced finishes. The 1c coin, known as the penny, is often included in these sets, highlighting its significance in American numismatics. Collectors value such coins for their rarity, condition, and historical context.
