Collectible coins include various categories such as historic coins, bullion coins, error coins, and commemorative coins. The United States has a rich numismatic history, with the 1 One Dollar denomination featuring notable designs and series. The Coronet Head cents, minted from 1816 to 1857, are particularly sought after, with the 1822 date being significant due to its limited mintage and collector demand. Coins from this era often exhibit intricate designs and serve as artifacts of their time, appealing to both history enthusiasts and numismatists.
