1880-CC

The 1880-CC eagle marks the eleventh year of $10 gold production at Carson City and lands in the middle of the mint's roughly two-decade run on the denomination. With a recorded mintage of 11,190 pieces, it sits among the more accessible Carson City eagle dates of the early 1880s, yet remains overwhelmingly scarce in collector terms, most surviving examples were spent into circulation in the silver-mining economy of western Nevada and never recovered. Strike quality is characteristically soft on the obverse stars and the eagle's neck feathers, a fingerprint of the worn working dies the branch mint typically used during this era.

Doug Winter has described the 1880-CC as fairly common up to about AU55 but genuinely difficult to locate above that grade with original color and undisturbed surfaces. Authentication should focus on the CC mintmark itself, since this date attracts added-mintmark fakes built from common Philadelphia 1880 hosts; the genuine punch shows two evenly spaced C's of consistent depth, with no tooled metal, raised seams, or color shift around the punch. A full-weight specimen reads 16.718 grams, with specific gravity in the 17.1 to 17.3 range, readings appreciably outside that window indicate a base-metal or low-karat counterfeit. Die-state markers, including the recurring weakness at the lower stars and the characteristic die polish lines through the reverse fields, also help separate genuine pieces from deceptive transfer-die copies.

Demand is driven largely by date-and-mintmark set builders and the durable Carson City following, which keeps prices firm even for circulated coins that would be afterthoughts if struck in Philadelphia. A PCGS AU55 example brought $6,600 at Heritage, while an AU58 from the Fairmont hoard realized $24,000 at Stack's Bowers, a clear illustration of how steeply the market values original-skin coins that survived in higher grades. Mint-state pieces are conditional rarities and trade in five figures when they appear at all, with most certified specimens concentrated in the VF to AU range and the population thinning sharply above AU55. Collectors building a Carson City eagle date set typically anchor around 1880-CC because the date is reachable in mid-grade circulated condition without the four- and five-figure stretch demanded by the truly rare CC dates of the 1870s.
