Collectible coins, also known as numismatic coins, are coins valued for their rarity, historical significance, or aesthetic appeal rather than just their metal content. The United States Mint produces various collectible coins, including the Silver Eagle series, which features the iconic Walking Liberty design. The 2017 Silver Eagle is a one-ounce silver coin with a face value of ten dollars, making it a popular choice among collectors and investors alike. These coins often come in various conditions, with "N A" indicating their grade, which influences their market value and desirability among collectors.
