Collectible coins encompass a wide range of numismatic items, including historical coins, commemorative issues, and rare variants. In the United States, collectible coins issued by the U.S. Mint include not only currency but also medals that celebrate significant events or figures in American history. The Julian catalog system provides collectors with a reference for identifying and valuing medals by assigning unique identification numbers, such as those from 1879, and some items remain unknown in terms of origin or specific details, adding an element of intrigue for collectors. The market for these types of collectibles can vary widely based on rarity, demand, and historical significance.
