Collectible coins, such as the Kennedy Half Dollar, represent a popular segment of numismatics in the United States. The Kennedy Half Dollar, introduced in 1964 following President John F. Kennedy's assassination, features his profile on the obverse and an eagle on the reverse. The 2006 Kennedy Half Dollar is part of a series that includes various mint marks and finishes, appealing to both collectors and investors. Collectors often seek coins based on rarity, condition, minting errors, and historical significance. The 50-cent denomination has maintained its status as a notable collectible due to its iconic design and limited mintage variations.
