Collectible coins, particularly from the United States, include a variety of denominations such as 1 cent (1c) and 50 cents (50c). Proof sets are specially minted coins characterized by their high-quality finishes and are often produced for collectors. The 1958 Proof Set from Philadelphia is notable for its inclusion of coins like the Lincoln penny, Jefferson nickel, Roosevelt dime, Washington quarter, and Benjamin Franklin half dollar, all struck to a superior quality and packaged in a protective case. These sets are popular among numismatists due to their limited mintage and striking aesthetics.
