Collectible coins can encompass a variety of types, including bullion coins, proof coins, and commemorative coins. The United States Mint produces a range of collectible coins, including the $100 Platinum Eagle, which features a design that showcases the symbolic representation of liberty and is struck in .9995 pure platinum. These coins often hold value beyond their face value due to their precious metal content and unique designs, making them sought after by numismatists and investors alike. The $100 Platinum Eagle is part of a series that highlights the versatility of platinum in coinage, and its limited mintage can enhance its collectibility.
