Collectible coins encompass various categories, including historical, numismatic, and thematic pieces. In the United States, the 1 Cent Penny is a notable example, with significant issues such as the 1819 counterstamped coins, which are coins that have been intentionally marked by a private individual or entity, adding a unique element to their collectible value. These types of coins often attract collectors due to their rarity, historical significance, or distinctive features, contributing to the vibrant world of numismatics.
