Collectible coins, especially those from the United States, include a variety of types such as commemorative coins, bullion coins, and denomination coins reflecting historical significance. The U.S. Mint produces not only currency but also medals that honor significant national events and figures. Medals like the Julian, linked to the coinage expert and author, can hold collectors' interest due to their historical context. The 1909 Philadelphia coinage is particularly notable for including the first Lincoln penny, which marked an important change in American numismatics and remains highly sought after by collectors.
