1910-S

San Francisco's 1910 production ran to 2,128,250 double eagles, a continuation of the high-volume pattern from 1909-S and again the dominant share of the year's denomination output across all three mints. The S mint mark appears above the date on the obverse. 1910-S carries the standard Motto-era design: low-relief Saint-Gaudens obverse with 46 stars, eagle-and-sun reverse with IN GOD WE TRUST above the sun, and lettered E PLURIBUS UNUM edge. The coin represents the second consecutive year of high-volume San Francisco production, reinforcing the branch mint's emerging role as the primary coining facility for the denomination during the pre-WWI era. Striking proceeded without documented production anomalies; no major die breaks, overdates, or hub errors are catalogued for this date.

Strike quality on 1910-S is generally strong; San Francisco die work at this date produced sharp central detail on Liberty and the eagle, with clean separation on the eagle's primary feathers and full definition on the Capitol rays behind Liberty. Bag marks on the obverse fields are the usual grading variable because these coins moved hard in commerce and in storage bags. Wear patterns follow the series: Liberty's forward knee, breast, and the eagle's breast feathers are first to show friction. Grade distribution is heavily weighted toward VF through MS64, which accounts for the bulk of market supply, with condition rarity becoming a sharp factor at MS65 and especially MS66 and finer. PCGS and NGC populations drop steeply above MS65, and the 1910-S in MS66 and higher is a legitimate condition rarity despite the original 2-million-plus mintage. Counterfeit exposure is the common-date Saint-Gaudens baseline, and certification is the standard acquisition path.

Market position for 1910-S is common-date through MS64 and genuinely scarce at MS66 and above, a gap that collectors should understand before making an acquisition decision. At MS63 and MS64, pricing tracks gold content plus a modest numismatic premium and dealers carry routine inventory. At MS66, the same date jumps sharply into five figures, reflecting how few examples of the original mintage have survived without bag marks, subdued luster, or surface issues. European bank hoard returns are the reason Mint State coins exist in quantity; the 1910-S was a regularly shipped date to overseas reserves, and repatriation from those storage lots from the 1950s onward is what fills current market supply. For date-and-mint set builders, the 1910-S is a straightforward acquisition at common grades. Registry-set collectors pay premiums that separate MS66 and higher pricing from the common tier by orders of magnitude. Acquisition is certified only at any grade, with CAC approval adding meaningful value at MS65 and finer.
