Collectible coins encompass a wide range of categories, including bullion coins, historical coins, error coins, and commemorative coins, each appealing to different collectors based on rarity, age, and historical significance. In the United States, coins issued by the U.S. Mint, such as the Morgan dollar and American Eagle series, are particularly sought after. Medallic Art medals, created by the Medallic Art Company, feature artistic designs and are often collected for their craftsmanship and aesthetic appeal. Coins and medals dated 1923 can hold varying levels of interest, depending on their mint condition, rarity, and numismatic value, although specific details about a particular piece marked as "Unknown" would require further examination for accurate appraisal.
