1880-S 80/79

The 1880-S 80/79 is the San Francisco overdate variety paralleling the 1880 Philadelphia 80/79 and 1880-O 80/79 issues. The variety belongs to the same 8,900,000-piece 1880-S mintage and reflects the same early-1880s die-reuse pattern that produced overdates across all three operating mints. Van Allen-Mallis attributes multiple VAM listings for the 1880-S 80/79 depending on the strength of the underlying 9. The variety carries the standard Reverse of 1879 hub, and the underlying remnants of the 9 from the 1879-prepared working die are visible beneath the 0 of the corrected 1880 date.

Authentication turns on the final digit. Under five to ten power magnification, the upper loop of the underlying 9 protrudes through the 0, visible above and slightly to the right of the 0's interior. The stronger varieties show clearer remnants and command higher premiums. PCGS, the Professional Coin Grading Service, and NGC attribute the strongest VAM examples in their slabs. The 1880-S 80/79 benefits from the broader San Francisco strike-quality pattern, so the variety preserves better central detail than the matched 1880-O 80/79 even at comparable Mint State grades.

The 1880-S 80/79 is a popular series Variety pickup that pairs with the 1880 Philadelphia 80/79 and 1880-O 80/79 in collections that target the year's overdate progression across all three mints. Pricing trades at a meaningful premium over the standard 1880-S across all Mint State grades, with the differential widest at MS64 and above. Most certified examples grade MS63 to MS65; MS66 and above is genuinely scarce. Certified slabs from PCGS or NGC with the VAM attribution noted on the holder are the standard purchase route at any meaningful price level, since variety counterfeits and misattributions both circulate in the raw market. The Van Allen-Mallis attribution system catalogues every documented Morgan die marriage, and the Top 100 Morgan VAM register identifies the most-collected varieties for specialist collectors.
