Collectible coins encompass a wide range of numismatic items that are valued for their historical significance, rarity, and condition. In the United States, specific types include the $3 gold coin, often referred to as the "Three Dollar" piece, minted primarily from 1854 to 1889. Buffalo Nickels, officially known as Indian Head Nickels, were produced from 1913 to 1938 and feature a Native American on one side and a buffalo on the other, symbolizing American heritage. The year 1916 marks specific issues in various coinages, including the Mercury Dime and the Standing Liberty Quarter, which can also be of interest to collectors.
