1858-S

San Francisco's 1858 double eagle production of 846,710 pieces continued the branch mint's pattern of high-volume Type I S-mint output that had been established with the 1855-S 879,675 figure. The output exceeded the 211,714 contemporaneous Philadelphia mintage by roughly 4 to 1 and dwarfed the 35,250-piece 1858-O, continuing the late-1850s pattern of San Francisco serving as the primary mint for the denomination. California gold flowed steadily through the West Coast facility despite the broader financial disruption from the Panic of 1857 affecting eastern commerce. Design specifications are unchanged from prior Type I S-mint issues. The S mint mark sits below the eagle on the reverse, the standard Liberty Head double eagle position.

Strike quality on 1858-S is typical for San Francisco's late-1850s Type I Liberty Head production, with adequate to good central detail on Liberty's coronet and the eagle's primary feathers on most well-preserved examples. Late-die-state coins occasionally show some softening in Liberty's hair detail; the issue does not display the pronounced die-wear patterns of some earlier S-mint dates. Wear on circulated examples follows the series pattern, with Liberty's hair above the ear, the coronet, and the eagle's shield and breast feathers first to show friction. Survival favors circulated grades through AU; Mint State examples are scarce, with MS62 and finer pieces individually significant when offered. Counterfeit exposure tracks the Type I baseline; PCGS or NGC certification is the standard authentication path for any 1858-S priced above bullion floor.

Market position for 1858-S is one of the more accessible Type I S-mint issues, with pricing through MS62 comparable to the 1855-S and 1856-S dates and reflecting the high original mintage and steady survival profile. Pricing in VF through AU runs in the mid four figures, MS60 reaches the high four to low five-figure range near $8,000 to $9,000, and MS63 sits near $50,000 at current market. MS64 and finer examples are condition rarities for any Type I date. For type-set collectors, the 1858-S functions as a Type I S-mint representative at competitive pricing with the Philadelphia alternatives. For date-and-mint set builders, it is a routine acquisition typically handled in the AU through MS62 grade range. Acquisition is certified only at this unit value.
