1879-CC

Among the Carson City double eagles, this issue sits second only to the legendary 1870-CC for lowest reported mintage. Doug Winter places it firmly inside his "Big Five" rarity tier alongside the 1871-CC, 1878-CC, 1885-CC, and 1891-CC, where it ranks roughly third in overall rarity behind the 1871-CC and 1878-CC. Surviving population estimates from Rare Gold Coins fall in the 300 to 400 range, the great majority concentrated in the VF35 to AU50 band. Mint State coins are nearly mythical: Winter believes fewer than ten legitimate Uncirculated pieces exist, and the few that do typically grade MS60 or MS61 with a meaningful drop-off above that.

Strike quality reflects the working conditions at Carson City in the late 1870s. Dies were used until they failed, and 1879-CC double eagles characteristically show softness on Liberty's hair curls, the eagle's wing tips, and the centers of the shield. Heavy bagmarks from cross-country shipment in canvas sacks are the rule rather than the exception, and original surviving luster is unusual on any coin grading below AU. The finest known example is the PCGS/CAC MS62 specimen from the 2012 Battle Born collection, which realized $74,750 at the time and has been estimated by Winter at well over six figures in the current market. At the more attainable AU level, the site's reference of a PCGS AU53 bringing $33,600 at Heritage in January 2020 remains a useful benchmark.

Authentication is non-negotiable here. Carson City mintmarks are among the most frequently added counterfeit features in American numismatics, and forgers have been observed welding or epoxying CC marks to common-date Philadelphia twenties from 1879. PCGS and NGC encapsulation is effectively required for any serious purchase, and CAC verification provides additional assurance on coins where surfaces or color have been a question.
