1988 United States Mint Proof Set

This is a 1988 United States Mint Proof Set, containing five circulating coin denominations minted to proof standards. The set includes a Kennedy Half Dollar, a Washington Quarter, a Roosevelt Dime, a Jefferson Nickel, and a Lincoln Cent. Each coin features the 'S' mint mark, indicating they were produced at the San Francisco Mint. The coins are characterized by a 'cameo' effect, where the raised design elements have a frosted, matte finish that provides a sharp contrast against the highly polished, mirror-like backgrounds. The cent is composed of copper-plated zinc, while the others are standard copper-nickel clad compositions. The set is housed in its original rigid plastic lens with a textured purple card insert, which bears the silver-scripted text 'United States Mint Proof Set' and 'PACKAGED BY U.S. MINT'. The protective case appears to be in good condition with minor surface scuffing common for its age, while the coins themselves appear well-preserved within the airtight environment, showing no visible signs of post-minting wear or heavy oxidation. This set represents the mid-to-late 20th-century era of American numismatic presentation.
