1987 United States Proof Set, 5 Coins Inside!!. The 1987-S Proof Set has the third highest mintage of any Proof Set in the 1980s. The major reason for this strong collector demand was that no Kennedy Half Dollars were placed into circulation, and they were only available in the Proof Sets and Mint Sets.Each set contained five coins: One example each of the Lincoln Cent, Jefferson Nickel, Roosevelt Dime, Washington Quarter, and Kennedy Half Dollar.About the sets: All coins in the 1987-S Proof Set were intended to have a Cameo or Deep Cameo Finish.Mintage: 3,792,233 setsOriginal packaging: The coins of the 1987-S Proof Set were placed in individual holes in a purple-colored, textured paper and cardboard insert, then sealed in a two-piece, clear plastic case. The case was then inserted into a protective outer cover, consisting of purple cardboard, imprinted with the somewhat confusing silver words: "United States Proof Set • 1987."
