The Kennedy Half Dollar is a 50-cent coin minted in the United States, first issued in 1964 to commemorate President John F. Kennedy following his assassination. The 2009 Kennedy Half Dollar coins were part of a limited mintage that marked the 50th anniversary of the series, featuring redesigned reverses. Collectible Kennedy Half Dollars vary in value based on their minting year, condition, and rarity, with certain coins from 2009 being sought after by numismatists for their unique design elements and lower production numbers.
