Collectible coins include various categories, such as historical coins, commemorative coins, and bullion coins, often sought after by collectors and investors. The United States has a rich numismatic history, with the 50 cents denomination, including the Kennedy Half Dollar, first issued in 1964 to honor President John F. Kennedy following his assassination. The 1979 Kennedy Half Dollar, while not particularly rare or valuable compared to other years, is part of the series that continues to attract interest from collectors, and its market value may vary based on condition and demand.
