Collectible coins, such as the 1978 Kennedy Half Dollar minted in San Francisco, are often sought after by numismatists due to their historical and aesthetic value. The Kennedy Half Dollar, introduced in 1964, honors President John F. Kennedy following his assassination. The 1978 issue, produced at the San Francisco Mint, is typically available in both regular circulation strikes and higher-quality proofs. Collectors often focus on factors such as mintage, condition, and unique characteristics when assessing the value and desirability of these coins.
