Collectible coins, also known as numismatic coins, include various types such as commemorative coins, rare mintages, and historical pieces. The five cents nickel, often referred to as the "nickel," has been a staple of U.S. coinage since its introduction in the 19th century. The half dime, once in circulation, was phased out with the introduction of the nickel. Coins from the Philippines under U.S. sovereignty, particularly during the early 20th century, hold significance for collectors due to their unique historical context and limited mintage. The 1931 coins are particularly notable for their rarity, with certain issues being highly sought after by collectors.
