Collectible coins encompass a variety of types, including commemorative coins, bullion coins, and proof sets. The United States offers a range of collectible coins, such as the 1-cent (penny) and 50-cent (half dollar) denominations, which are often sought after by numismatists. Proof sets, particularly from 1964, are highly valued due to their limited mintage and enhanced quality, featuring coins that have been struck with greater care to achieve a mirror-like finish. These sets typically include coins from various denominations minted that year, showcasing their historical significance and appeal to collectors.
