1880 80/79

The 1880 80/79 is the principal Philadelphia overdate variety of the third Morgan Dollar year, struck from dies that the Mint had prepared with 1879 dates and then partially re-engraved to 1880 when production schedules pushed Treasury to reuse leftover working dies rather than discard them. The result is a coin where the underlying 9 of the 1879 die remains visible beneath the 0 of the corrected 1880 date, a textbook overdate condition that Van Allen-Mallis attributes through multiple VAM listings. The variety belongs to the same 12,601,355-piece 1880 Philadelphia mintage that produced the standard 1880 and other doubled-die varieties.

Authentication of an 80/79 claim turns on the final digit of the date. Under five to ten power magnification, a genuine 80/79 shows the upper loop of the underlying 9 protruding through the 0, visible above and slightly to the right of the 0's interior. Several VAM listings exist depending on the strength of the underlying 9, with the stronger varieties (VAM-6, VAM-7) commanding the highest premiums. PCGS, the Professional Coin Grading Service, and NGC attribute the strongest VAM examples in their slabs. Counterfeit overdates exist; verify weight at 26.73 grams and a clean reeded edge before paying any premium.

The 1880 80/79 is a popular series Variety pickup that trades at a meaningful premium across all Mint State grades and pairs naturally with the 1880-O 80/79 and 1880-S 80/79 in collections that target the year's overdate progression across all three operating mints. Most certified examples grade MS62 to MS64; MS65 and above is condition-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.
