Collectible coins are items sought after by numismatists and collectors for their historical significance, rarity, and condition. In the United States, fifty-cent coins, known as Kennedy Half Dollars, were first minted in 1964 to honor President John F. Kennedy following his assassination. The 2011 Kennedy Half Dollar is part of the series that continues to be produced for circulation, though in limited quantities; however, many coins from this series are sought after in uncirculated or proof condition. These coins are often collected not only for their face value but also for their numismatic value, particularly those that exhibit unique characteristics or limited mintage.
