Collectible coins encompass a variety of coin types, including numismatic coins, bullion coins, and commemorative coins. In the context of the United States, notable collectible items include the 1-cent coin (1c), commonly known as the penny. Proof Sets, such as those from 2017, are specially minted collections that feature coins with a high-quality mirror finish, emphasizing detail and artistry. These sets often appeal to collectors for their aesthetic value and limited mintage.
