Collectible coins, particularly those from the United States, encompass a wide range of types, including historical currency, commemoratives, and various denominations such as the 10-cent (dime) and 1-dollar coins. Proof sets, including the 2022 edition, consist of specially minted coins characterized by their high-quality finish and sharp details, often sought after by collectors for their aesthetic appeal and limited availability. These sets typically include coins from different denominations, showcasing both historical significance and investment potential. Collectors often focus on both the numismatic value and the condition of the coins within the sets for their collections.
