1856-O

The 1856-O eagle is the sixteenth-year New Orleans issue in the Liberty Head ten-dollar series, struck to a tiny mintage of just 14,500, one of the lower production figures in the entire NO No Motto run. Doug Winter places this date in the high-grade rarity tier alongside the 1849-O, 1852-O, and 1857-O, noting it "barely misses qualifying for Tier One status" and is "every bit as rare in higher grades as more heralded dates in the No Motto series." He calls it a true appearance rarity that has quietly fallen under the collector radar. Survivors are estimated at well under one percent of the original mintage, with most extant pieces residing at the VF level and any AU55-or-better example with original color qualifying as a major condition rarity.

Authentic 1856-O eagles weigh 16.718 grams in 90% gold with a specific gravity near 17.2, and the O mintmark sits below the eagle on the reverse. Three minor mintmark-placement varieties have been documented for the date, surprising given the small mintage, and any examination should begin there. Strike is below average for the issue: most coins show heavy obverse abrasion and a soft strike on Liberty's curls, and the natural coloration runs to an orange-gold cast that is distinctly different from the 1855-O. Original, choice surfaces are scarce in the extreme; Winter notes recent price softness in AU55 and AU58 reflects the quality of coins offered rather than any genuine increase in supply. Combined PCGS and NGC populations show a small handful of Mint State pieces, with MS60 standing as the practical ceiling for the date.

For tier-aware collectors, the 1856-O is the kind of date that rewards patience, a genuinely rare NO No Motto eagle whose price guides have lagged the population data, leaving room for upside on truly original examples. VF and EF coins with honest wear remain available at lower five figures and represent the realistic entry point; AU coins with original surfaces are the prize and command meaningful premiums when they surface at auction. Mint State examples are a once-in-several-years opportunity. For broader context on Type 1 branch-mint production and the New Orleans No Motto run, see the Liberty Head Eagle series history.
