Collectible coins are often sought after by enthusiasts and investors for their historical significance, rarity, and aesthetic appeal. The United States Silver Eagle, particularly the 2005 edition, is a notable example of a collectible coin, produced by the U.S. Mint. One Dollar Silver Eagles contain one troy ounce of pure silver and feature iconic designs, making them popular among both collectors and bullion investors. The designation "N A" typically indicates that the coin is not applicable for a particular grading standard or that it lacks a numerical grade due to its unique attributes.
