1855-S

The 1855-S is the second-year San Francisco eagle, and the year that exposed how thin the new branch's gold-coin output really was. Production at the Pacific facility collapsed from 123,826 pieces in 1854 to just 9,000 in 1855, a drop of more than 90 percent, as the mint redirected bullion toward the larger double eagle denomination that California commerce actually demanded. The result is one of the lowest mintages anywhere in the Liberty Eagle series and a coin whose absolute scarcity outweighs its first-year sibling's historical fame. Where the 1854-S survives in the low hundreds, the 1855-S survives in the dozens, and the disparity in availability between the two consecutive dates is among the most extreme in branch-mint gold.

Survival counts published by Douglas Winter place the population at roughly fifty to sixty examples in all grades, with most concentrated in VF30 to EF45. About Uncirculated pieces are decidedly rare, with perhaps ten to twelve known across both major services, almost all grading AU50 to AU53 with heavy abrasions consistent with the date's circulation history. AU55 examples can be counted on one hand, PCGS reports a single AU58, and no Mint State coin has been certified by either grading service. Authentication is critical at this rarity level. Confirm the statutory weight of 16.718 grams and specific gravity near 17.2 to rule out struck copies, examine the S mintmark for the period punch geometry and natural die-sunk relief that rules out an added mintmark from a common Philadelphia 1855, and expect the prooflike bagmarked surfaces typical of San Francisco gold rather than mishandled fields suggestive of a cleaned or repaired piece. Original-skin coins with even circulated wear are uncommon enough to command meaningful premiums.

The collecting case rests on the gap between rarity and price. With low-AU examples typically trading in the mid-four to low-five-figure range, the 1855-S sells for a fraction of what comparable pre-1879 San Francisco eagles bring at similar census positions, and Winter has flagged the date as undervalued for years. For the date collector, an AU50 or better with original surfaces represents one of the more achievable genuine rarities in the No Motto series.
