1970 United States Proof Set

This is a 1970 United States Proof Set, consisting of five coins minted at the San Francisco Mint. The set includes a Lincoln penny, a Jefferson nickel, a Roosevelt dime, a Washington quarter, and a Kennedy half dollar. Each coin features a mirror-like 'proof' finish with sharp, frosted relief against polished backgrounds. The Kennedy half dollar is particularly notable for being composed of 40% silver, the final year for this circulating denomination to contain precious metal. The coins are housed in a formal black plastic insert featuring the silver eagle emblem of the U.S. Mint, all encapsulated within a transparent, hard plastic protective case. The 'S' mint mark is visible on the coins, indicating their origin. The condition appears well-preserved with no significant evidence of PVC damage or heavy oxidation; however, some light haze is typical for sets of this era. The plastic case shows minor external scuffing consistent with age and handling. This set represents a high-quality production standard intended specifically for collectors, showcasing the technical numismatic artistry of the late 20th century.
