1906-S

San Francisco's gold coiners pressed on through one of the most disruptive years in the city's history, and the surviving Type 3 Double Eagles from this date carry that backstory. The Great Earthquake struck on April 18, 1906, and the resulting fire leveled much of the city around the Mint at Fifth and Mission. Frank A. Leach's "Granite Lady" stood, sheltering roughly a third of the nation's gold reserves, and after the gas works were restored the presses began running again. The Coronet $20 had become a workhorse, and 1906 was the calendar in which Denver opened a third coining facility, joining the existing Philadelphia and S-mint output and reshaping how the federal government distributed gold-coin production across the country.

For collectors, this S-mint issue lives in the band of relatively available Type 3 dates from the early 1900s, slotted between the 1905-S production of 1,813,000 and the 1907-S figure of 2,165,800. PCGS describes the strike as generally sharp on the obverse, with occasional softness on the radial star lines, while reverse centers can show slight weakness even as the peripheries remain crisp. Surfaces are typically lustrous but moderately abraded from rough commercial handling, and color tends to range from a light rose-gold to a deeper orange-gold cast. The finest known example, an MS67, is the Clapp-Eliasberg coin reportedly obtained directly from the San Francisco Mint in 1906.

Population data confirms the condition-rarity profile that defines this issue. Heritage Auctions has cited PCGS at 1,281 in MS63 with 331 finer, alongside an NGC census of 659 in MS63 with 118 finer, illustrating a steep falloff above the choice level. Gem material is genuinely scarce, and superb gems remain elite. Specialists who pursue date-and-mint sets generally prize the 1906-S as a coin whose ordinary preservation belies its extraordinary moment in California history, an artifact tied directly to one of the great urban disasters of the century.
