1910

Philadelphia's 1910 double eagle production came in at 482,167 pieces, roughly triple the 1909 Philadelphia mintage and the largest annual output at the parent mint since the 1908 No Motto surge. Production followed the established pattern for the Motto era: low-relief Saint-Gaudens dies with Arabic-numeral date, 46 obverse stars reflecting the pre-statehood configuration still in force at the time, and the eagle-and-sun reverse with IN GOD WE TRUST above the sun. No mint mark appears because Philadelphia coins of the series carry none. Matte Proof specimens of the 1910 date were also struck in small numbers as part of the 1908-1915 Philadelphia proof program, though proof coins are tracked separately from business strikes and are not included in that production figure. The 1910 falls in the late portion of the 46-star era (1907-1911) before the 1912 hub change added two stars for New Mexico and Arizona.

Strike quality on 1910 is typical for Philadelphia Motto-era production: central detail on Liberty's torch, skirt drapery, and the eagle's breast feathers comes up cleanly on most examples. Die wear is not a particular concern for this date, and die breaks or cracks are not commonly observed on known examples. Wear on circulated coins concentrates on Liberty's forward knee, breast, and the eagle's breast and leading wing, following the standard series wear pattern. Surface preservation is the principal grading variable because the design holds up well against friction; the fields are clean and the devices are sharp on well-preserved coins. Counterfeit risk tracks the common-date Saint-Gaudens baseline, elevated enough by the coin's unit value that PCGS or NGC certification is the standard practice. Matte Proof 1910 coins are a separate class entirely, with their characteristic sandblast finish and proof-specific surface qualities, and any example trades at six-figure pricing.

Market position for 1910 Philadelphia is that of a common-date Saint-Gaudens, available in all circulated grades and readily accessible through MS64 at pricing driven mainly by gold content plus a modest numismatic premium. European bank hoard returns are the principal reason Mint State coins remain plentiful today; domestic survivors were largely melted during and after the 1933 gold recall, and repatriated overseas coins filled the supply that collectors encounter. Condition rarity becomes a real factor at MS66 and above, where population figures tighten considerably and registry-set competition drives pricing well above common-grade levels. For date-and-mint set builders, the 1910 is a routine acquisition that usually comes last on the shopping list because availability makes it an easy check-off. Certified MS63 or MS64 is the practical entry point, and CAC approval adds marginal value at the higher grade tiers but is not essential at the common grades.
