Collectible coins refer to specific pieces of currency that are sought after by numismatists and collectors due to their rarity, historical significance, or unique features. In the United States, half dollars, particularly those produced in 1977, can be part of a 50-cent roll, which contains multiple coins stored together for convenience or sale. The 1977 half dollar features the depiction of John F. Kennedy on the obverse and the Presidential Seal on the reverse, making it a popular choice among collectors, especially those focusing on modern U.S. coins. Collectors often seek out specific mint marks, conditions, and varieties to enhance their collections.
