Collectible coins from the United States, such as the 1 cent (penny) and 50 cent (half dollar), are sought after by numismatists. They can come in various conditions, with Proof Sets from 1992 being particularly notable. Proof Sets, which include coins struck with a higher quality finish, are often collected due to their aesthetic appeal and limited mintage, adding to their rarity and value in the collectible market.
