Collectible coins, such as the Kennedy Half Dollar, represent unique pieces of numismatic history. The United States issued the Kennedy Half Dollar in 1964, following President John F. Kennedy's assassination. The 1978 Kennedy Half Dollar is part of a series that continues to commemorate Kennedy's legacy. Collectors seek various editions, mint marks, and conditions, with specific years, like 1978, potentially holding differing values based on rarity and demand. The 50-cent coin holds appeal for both historical significance and investment potential among numismatists.
