Collectible coins, particularly from the United States, encompass a wide variety of types and series, with specific interest in Half Dollars. The 50-cent pieces from 1979, minted in Philadelphia, are part of the Kennedy Half Dollar series, which was first introduced in 1964. These coins often attract collectors due to their historical significance and connection to the iconic President John F. Kennedy. The Philadelphia mint's production marks can affect their value, with uncirculated or proof versions being more sought after in the market. Collectors often seek out original rolls containing these coins for both their numismatic value and as an investment.
