Collectible coins are a category of coins valued above their face value due to their rarity, historical significance, or desirability among collectors. The Kennedy Half Dollar, introduced in 1964, honors President John F. Kennedy and remains popular among numismatists. The 2001 Kennedy Half Dollar, produced in honor of his legacy, is often sought after for both its design and possible mint variations. The 50 Cent coin, particularly in uncirculated or proof condition, can command higher prices depending on its availability and demand within the market.
