Collectible coins, particularly U.S. coins, can have significant historical and monetary value. The Kennedy Half Dollar, introduced in 1964, commemorates President John F. Kennedy. The 50-cent pieces minted in 1965, especially those produced in San Francisco, are notable for their lower silver content, as they transitioned to a clad composition. Coins from this era, especially in high grade or specific mint marks, can be sought after by collectors for their unique attributes and connection to American history.
