2004-S Silver Proof

San Francisco struck 1,175,934 Kennedy half dollars in 90% silver for the 2004 Silver Proof Set, the highest mintage of any silver proof Kennedy since the 1992 inaugural year of 1,317,579. The figure caps the program's mid-decade strength alongside the 2003 figure of 1,125,755 and the 2005 figure of 1,069,679, the only stretch of consecutive million-plus silver proof Kennedy production outside the 1992 first year. Silver spot prices continued their climb through 2004, drawing bullion-conscious buyers into Silver Proof Set subscriptions even as the State Quarter program kept set demand structurally elevated. Composition follows the restored pre-1965 recipe of 90% silver and 10% copper at 12.50 g and 30.6 mm with a reeded edge, carrying 0.36169 troy ounces of actual silver weight per coin.

Authentication separating the silver coin from its cupronickel-clad sibling in the standard 2004 Proof Set rests on three tests. Edge inspection shows uniform silver reeding on the silver issue and a copper-colored line through the clad rim from its exposed core. Weight runs 12.50 g for the silver and 11.34 g for the clad, a 1.16 g difference any small scale will resolve. Specific gravity confirms the planchet alloy if a precise reading is needed. Cameo and Deep Cameo describe the contrast between mirrored proof fields and frosted devices, designated CAM and DCAM by PCGS, the Professional Coin Grading Service, and Cameo and Ultra Cameo by NGC, Numismatic Guaranty Company. By 2004 the Mint's proof-die preparation produced full deep cameo on essentially every San Francisco silver strike, putting PR69 DCAM at the floor of the certified market for the issue.

As a collecting target the 2004-S silver proof trades in PR69 DCAM at a modest premium over melt value, with the meaningful price step at PR70 DCAM where surface preservation under loupe inspection separates technically identical coins. Original Silver Proof Set packaging surfaces routinely. Three buyer pools share the market: type-set collectors needing one 90% silver Kennedy from the modern reintroduction era, year-set builders working 2004 issues across denominations (including the year's five State Quarter silver designs), and bullion-conscious collectors who hold the issue partly for its 0.36169 troy ounce silver content. The 1,175,934 mintage represents the highest non-inaugural figure of the 1992 through 2005 silver run but carries no scarcity premium because supply meets demand comfortably at this production level.
