Collectible coins refer to numismatic items that are sought after by collectors and investors due to their rarity, historical significance, or unique features. One notable type is the Kennedy Half Dollar, which was first issued in 1964, commemorating President John F. Kennedy. The 1972 Kennedy Half Dollar, particularly those minted in San Francisco, can be found in both standard and proof varieties, with the latter often exhibiting higher quality and collectible value. The 50-cent coins from this series are part of the United States' numismatic landscape and are popular among collectors for their design and historical context.
