1855

Philadelphia struck 364,666 double eagles in 1855, the lowest Type I Philadelphia output to that point in the series and less than half the prior year's combined 757,899 production. The continuing mintage decline reflected the gradual exhaustion of California placer gold supply and the parallel buildout of San Francisco Mint capacity that drew bullion processing toward the West Coast rather than the parent mint. Production at Philadelphia in 1855 paired with a famously rare 8,000-piece New Orleans output and a 879,675-piece San Francisco issue, with San Francisco taking over the volume role that Philadelphia had previously occupied. Design specifications are unchanged from prior Type I Philadelphia issues: Liberty Head obverse with thirteen stars and date, heraldic eagle reverse with shield and TWENTY D., reeded edge, Longacre's JBL initials on the bust truncation.

Strike quality on 1855 Philadelphia is generally good, with crisp obverse star definition and full coronet detail on most well-preserved examples. The lower production volume relative to 1851-1854 means die-state issues are less pronounced for this date than for the high-mintage early Type I issues. 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 MS63 and finer pieces individually significant when offered. European bank hoard returns supplied a meaningful portion of the surviving Mint State population. Counterfeit exposure tracks the Type I baseline; PCGS or NGC certification is the standard authentication path for any 1855 priced above bullion floor.

Market position for 1855 Philadelphia sits as a moderate-availability Type I issue, less common than the 1850-1854 Philadelphia dates but still readily acquired in circulated grades. Pricing in VF through AU runs in the mid four figures, MS60 reaches the high four figures near $10,000, and MS63 sits near $60,000 at current market. MS64 and finer examples are condition rarities for any Type I date. For type-set collectors, the 1855 is a workable Type I representative at slightly higher pricing than the 1850-1854 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.
