1987-S Proof

San Francisco struck 4,227,728 Kennedy half dollar proofs in 1987, the highest 1980s figure for the date and a notable counterpoint to the year's parallel circulation-side production story. 1987 was the first year the U.S. Mint did not strike Kennedy halves for general circulation; Philadelphia and Denver produced their entire 2,890,758-piece runs for the year's Uncirculated Mint Set only, leaving 1987 P and D as mint-set-exclusive issues. The proof program at San Francisco operated entirely independent of that decision, so 1987-S proof output actually rose above the prior year's level rather than falling. The proof set therefore became the most accessible source of any 1987-dated Kennedy half for collectors who could not or did not order the year's mint set. Composition follows the standard post-1971 recipe: 75% copper and 25% nickel outer layers bonded to a pure copper core, 11.34 grams at 30.6 millimeters, with a reeded edge. Roberts's GR initials remain at the truncation of Kennedy's neck and Gasparro's FG sits to the right of the eagle's tail feathers.

What collectors actually chase on the 1987-S is Cameo and Deep Cameo contrast rather than the basic proof finish. Cameo, abbreviated CAM on slabs from PCGS, the Professional Coin Grading Service, and from NGC, Numismatic Guaranty Company, refers to the visual effect where the mirrored fields stay glassy black while the frosted devices read matte white under angled light. Deep Cameo, or DCAM, is the strongest version of that contrast. By 1987 DCAM was firmly the production norm on fresh proof dies, so the higher mintage produced a correspondingly deep PR69 DCAM census and pushed the genuine condition target up to PR70 DCAM. Diagnostics worth checking under good light include the depth of frost on Kennedy's hair flow above the ear, the matte texture on the eagle's chest feathers, and the unbroken mirror field around the motto lettering and the date. The 4.2-million mintage is deep enough that the contrast hunt rewards patient submitters rather than driving any baseline scarcity.

For collecting purposes the 1987-S sits as a routine common gem proof, with the year's structural interest pulling collector attention toward the mint-set-only 1987-P and 1987-D rather than toward the proof. PR69 DCAM examples trade near the basic certified levels of adjacent 1986-S and 1988-S issues; PR70 DCAM remains the registry-set target and commands meaningful multiples in census terms because population reports thin sharply at that grade despite the high mintage base. Type collectors filling a late-1980s S-mint slot can buy raw proof sets cheaply. The independence of proof production from the circulation-side mint-set-only decision is the year's clearest analytical point.
