The coin in question is a 2014 Kennedy Half Dollar, produced at the San Francisco Mint. This particular version is a proof coin, which means it was struck with higher quality and finish, making it more reflective and detailed than regular circulation coins. The Kennedy Half Dollar, featuring the iconic portrait of President John F. Kennedy, is a 50-cent coin (denomination of 50¢), and is made from Copper-Nickel clad Copper, which gives it a distinctive appearance and feel. This particular coin is notable for its mintage of only 665,100 units, indicating it was produced in relatively limited quantities compared to other years, which can add to its collectible appeal. The diameter of the coin is 30.6 mm, and it weighs 11.34 grams. As a product of the United States of America, it is part of a longstanding tradition of commemorative and circulating coins. Its unique proof finish and limited mintage make it an attractive option for collectors of numismatic items. The San Francisco Mint mark (denoted by the "S" on the coin) further identifies it as part of the special series produced at that Mint, adding to its historical significance. Overall, this 2014 Kennedy Half Dollar proof coin stands as a vivid reminder of American heritage, honoring the legacy of JFK while also serving as a valuable piece for collectors and enthusiasts alike.
