Collectible coins include various types such as commemorative, bullion, and circulating coins that may have unique historical significance or artistic value. The United States half dollar, often referred to as a 50-cent coin, is a popular collectible, with the 2017 Denver mint issue being particularly notable for its design and limited mintage. Collectors often seek out specific rolls of these coins for their quality and potential investment value.
