Collectible coins include a variety of types, with specific focus on coins produced by the United States Mint. The 50-cent coins, known as Kennedy Half Dollars, were first minted in 1964 in honor of President John F. Kennedy. The 1980 issue, particularly those minted in San Francisco, is notable for its limited mintage and is often sought after by collectors. These coins are typically valued based on their condition, rarity, and demand among numismatists.
