1891-CC

The 1891-CC $10 Liberty Eagle is the statistical outlier of the Carson City eagle series. Its 103,732-piece mintage exceeds every other CC eagle by a wide margin, and surviving population estimates of roughly 4,500 coins represent close to half of all known Carson City eagles across the entire 1870-1893 run. For collectors building a CC eagle date set, this is the entry that finally cooperates: examples surface routinely at auction, the grade ladder extends well into Mint State, and prices reflect a relative abundance that none of its sister dates can match.

The 1891-CC is the seventeenth CC eagle struck and the second-to-last issue from a mint that would close two years later. Despite the generous output, the date is genuinely scarce in choice condition: combined PCGS and NGC populations show only 140-170 coins certified MS-63, fewer than ten at MS-64, and a single NGC MS-65 that anchors the condition census. That MS-65 example crossed the Heritage block at a strong premium, while MS-63 and MS-64 specimens regularly bring five-figure results. Authentication centers on three checks. Confirm the specific gravity at approximately 17.2, copper or tungsten-core counterfeits diverge measurably. Verify the weight at 16.718 grams (tolerance 16.65-16.79g) and a 27mm diameter; lightweight or undersized examples are immediate red flags. Inspect the CC mintmark on the reverse below the eagle for proper serif structure and seating; the genuine punch sits cleanly within the field with no tooling around the base, and added-mintmark deceptions on Philadelphia 1891 hosts are the principal counterfeit threat for this date.

For collectors, the 1891-CC functions as the gateway Carson City eagle. It is the date most often recommended as a first acquisition for a CC type or short set, and it is also the date where condition rarity, rather than absolute rarity, drives value above the AU58/MS62 boundary. Circulated examples in VF-EF trade in proximity to numismatic premiums over melt, AU coins step up meaningfully, and any properly graded Mint State specimen deserves close diagnostic attention given the stakes. The date's ubiquity in the survivor pool makes it the workhorse of CC eagle collecting and the natural anchor of any Carson City gold cabinet.
