Collectible coins encompass a wide range of items, including historical, commemorative, and bullion coins. In the United States, half dollars (50-cent coins) are a popular category, particularly those minted in significant years or locations. The 1999 San Francisco half dollar is part of a series that often attracts collectors due to its unique mintmark and design, representing an era of U.S. coinage. Collectors often seek out entire rolls of these coins, which can provide both collectible value and potential investment opportunity.
