Collectible coins encompass a variety of types including commemorative coins, bullion coins, error coins, and coins from specific mintages. In the United States, popular collectible denominations include the penny (1 cent), often sought after in various conditions and mint marks. Proof sets, such as the 1989 Proof Set, are produced with a high-quality minting process, featuring a mirror-like finish and are typically made for collectors rather than general circulation. These sets often include coins from various denominations, making them desirable to numismatists.
