Collectible coins encompass a wide range of numismatic items, including patterns and trial coins. The 1856 pattern one cent penny, often referred to simply as the 1856 penny, is a notable example from the United States. This coin was created as a prototype for the new copper-nickel composition intended for the official penny, and only a limited number were produced, making it highly sought after by collectors. Its distinct features and historical significance contribute to its value in numismatics.
