Collectible coins, particularly those from the United States, encompass a wide range of categories, including numismatic coins, commemorative coins, and bullion coins. Numismatic coins are valued for their rarity, historical significance, and condition, while commemorative coins are issued to honor specific events or individuals. Bullion coins, such as the American Eagle and American Buffalo, are primarily valued for their metal content, typically gold or silver, and also appeal to collectors. The grading of these coins, often assessed by established standards like the Sheldon Scale, plays a crucial role in determining their market value among collectors.
