1850-O

The 1850-O eagle marks the tenth year of Liberty Head ten-dollar production at the New Orleans Mint, a decade-anniversary issue from a branch facility that had quietly become the country's most consistent supplier of $10 gold outside Philadelphia. With a recorded mintage of 57,500 pieces, the 1850-O fits the middle band of antebellum O-Mint eagles by output, but its survival profile sits well below what the figure suggests. Doug Winter ranks it among the third or fourth rarest No Motto New Orleans eagles overall, slotting behind only the 1841-O and 1859-O, and in the same conversation as the 1849-O for absolute scarcity. Roughly 200 to 400 examples are believed to survive across all grades, the vast majority worn down to Fine through Extremely Fine after decades of Mississippi-Valley commercial circulation.

For collectors, the diagnostics matter as much as the population. Authentic 1850-O eagles weigh 16.718 grams in 90% gold, with a specific gravity near 17.2 and a sharp, cleanly punched O mintmark on the reverse below the eagle. Strike on this issue is typically average for the New Orleans Type 1 era; Winter notes that finer pieces show "thick, frosty luster" beneath green-gold and orange toning, but most surviving examples display soft definition on the eagle's neck feathers and the upper hair curls. Properly graded AU55 coins are genuinely rare; AU58 borders on a condition rarity with only a handful of strict examples certified. Mint-State survivors are essentially museum-tier, Winter cites just three known Uncirculated, headed by the Eliasberg/Clapp/Earle PCGS MS65, with the rest off the market.

Within the No Motto O-Mint run, the 1850-O occupies the tier collectors target when an 1841-O or 1859-O is out of budget but a more available 1847-O feels too easy. A small handful of pieces emerged from the Fairmont Hoard, including the PCGS/CAC AU58 that realized $31,200 at Stack's Bowers in April 2022, currently the public benchmark for the date in choice circulated grade. Winter argues that even after Fairmont, choice AUs remain underpriced relative to the date's true rarity, making this an issue where condition discipline at acquisition pays off years later.
