Collectible coins encompass a variety of types, including the 1 One Cent Penny, which is a popular entry point for many collectors in the United States. Patterns and trial coins, such as the 1974 trial pieces, are also significant, as they serve as test strikes that showcase design variations and manufacturing processes prior to mass production. These unique items can be highly sought after due to their rarity and historical value in numismatics.
