Coins are physical currency items, often made of metal, issued by governments and used as a medium of exchange. Specifically, the United States features a variety of collectible coins, such as the Fifty Cents piece, including the modern commemorative coins minted to celebrate significant events or individuals. In 2011, for instance, a specific edition of the Fifty Cents coin was produced at the San Francisco Mint, contributing to the rich history and appeal of U.S. numismatics. Modern commemoratives often feature intricate designs and limited mintage, enhancing their desirability among collectors.
