Collectible coins often include various types, such as half dollars, which are significant in American numismatics. The United States half dollar has undergone various design changes, with notable issues like the Kennedy half dollar introduced in 1964. A 50-cent roll of coins typically contains 20 half dollars, totaling $10. The 1997 half dollar, part of ongoing minting programs, may feature unique characteristics, such as specific mint marks or finishes that can influence its numismatic value among collectors.
