Collectible coins, also known as numismatic coins, are primarily valued for their rarity, historical significance, and condition rather than their currency value. In the United States, collectible coins include a wide variety, such as gold, silver, and commemorative coins, as well as those minted for specific events or anniversaries. The “G 10” designation may refer to the grade of a coin based on its condition, with "G" typically indicating a grade of "Good," which denotes significant wear but still identifiable features. The term "Wass" could relate to variations, styles, or specific examples associated with collectible coins; further context would be needed for precise interpretation.
