Collectible coins, particularly from the United States of America, encompass a variety of types, including bullion, commemorative, and proof coins. One notable example is the American Platinum Eagle, first introduced in 1997, which is made from 99.95% pure platinum and is available in various denominations. The 1999 Platinum Eagle is particularly sought after by collectors due to its limited mintage and unique design features, making it a significant addition to any numismatic collection. Collectible coins often see their values increase over time, influenced by factors such as rarity, condition, and market demand.
