Collectible coins, particularly those issued by the United States of America, encompass various types, including the 50 cent denomination known as the Kennedy Half Dollar. Minted since 1964, the Kennedy Half Dollar commemorates President John F. Kennedy and features his profile on the obverse and the Presidential Seal on the reverse. The 2019 edition includes standard circulation coins as well as special releases, such as silver proofs or uncirculated versions, appealing to both numismatists and casual collectors alike. The term "Unknown" may refer to coins with uncertain mintage or provenance, highlighting the importance of documentation in collectible coin assessment.
