Collectible coins refer to coins that are sought after by collectors due to their historical significance, rarity, artistic design, or unique features. The Kennedy Half Dollar, introduced in 1964, commemorates President John F. Kennedy following his assassination. The 1981 Kennedy Half Dollar, minted in San Francisco, features the "S" mint mark and is part of the series that includes both proof and uncirculated versions. Minted in lower quantities compared to earlier years, these coins attract collectors and are valued based on their condition and demand.
