1859

Philadelphia struck only 43,597 double eagles in 1859, the lowest Type I Philadelphia mintage of the entire 1849-1866 No Motto era. The figure represents the bottom of the post-Panic-of-1857 production decline that began with 1858's 211,714 issue and continued through 1859 before the 1860 mintage rebounded to 577,670 pieces. The dramatic dip reflects a single-year contraction in bullion deposits to the parent mint as gold flows redirected toward the San Francisco facility and as broader economic conditions slowed. 1859 was the lowest Philadelphia output for the denomination until the 1880s when proof-only issues began appearing. Production at Philadelphia paired with a 9,100-piece New Orleans output and a 636,445-piece San Francisco issue, with San Francisco again accounting for the bulk of the year's coinage. Design specifications are unchanged from prior Type I issues.

Strike quality on 1859 Philadelphia is generally good, with crisp obverse star definition and full coronet detail on most well-preserved examples. The lower production volume meant fewer die passes overall, so die-state issues are less pronounced than for the high-mintage early Type I dates. Wear on circulated coins concentrates on Liberty's hair above the ear, the coronet, and the eagle's shield and breast feathers. Survival is weighted toward circulated grades through AU; Mint State examples are scarce, with MS62 and finer pieces individually significant when offered. The lower original mintage produced a correspondingly smaller surviving Mint State population than higher-volume years, contributing to the issue's semi-key pricing structure. Counterfeit exposure is moderate for 1859 given the price level; PCGS or NGC certification is the standard authentication path.

Market position for 1859 Philadelphia sits in the semi-key tier of the Type I subset, supported by both the low mintage and the modest surviving Mint State population. Pricing in VF runs near $4,500 to $5,000, EF examples reach $7,500 to $9,000, AU sits in the low to mid five-figure range above $10,000, and MS60 examples cross into the mid five-figure range above $27,000. MS63 examples sit near $80,000 at current market. Collector demand comes primarily from date-and-mint set builders treating the 1859 as a required Type I acquisition and from Type I Philadelphia specialists pursuing the complete pre-1866 No Motto run. Acquisition is certified only at this unit value given the steep grade-tier differentials.
