1846-O

New Orleans struck 62,000 quarter eagles in 1846, the highest mintage of the four 1846 Liberty Head quarter eagle issues and a figure that gives the date a different collecting profile from its branch-mint cousins. The Crescent City facility processed bullion arriving by river from southern gold districts and by sea from Mexico and the Caribbean, and 1846 fell within a productive period for the New Orleans coining presses. The quarter eagle saw active use in Gulf Coast commerce, with merchants and cotton factors handling gold coin as part of routine transactions in a port economy where paper currency from any single bank carried meaningful discount risk.

The O mintmark appears on the reverse below the eagle, distinctive in its slightly oval profile compared to the rounded C of Charlotte. Authentication centers on the mintmark itself, examined under 5x to 10x magnification for the characteristic New Orleans punch shape and the natural metal flow of an original strike. Counterfeit and altered O mintmarks appear regularly on lower-grade 1846 quarter eagles, where someone has added an O to a Philadelphia host coin to capture the New Orleans premium. The disturbed surface texture around an added mintmark, plus the wrong punch profile, gives the alteration away when examined carefully. Standard verification of the 4.18 gram weight and 18 millimeter diameter rules out struck counterfeits and base-metal reproductions.

For collectors, the 1846-O occupies the Semi-Key tier rather than full Key Date status, but the issue rewards patient searching. Most surviving examples grade Very Fine through Extremely Fine, reflecting the heavy circulation typical of New Orleans gold issues. Mint State coins exist but appear infrequently at auction, and original-skin examples with even golden patina draw competitive bidding when they surface. Strike quality runs better than the southern branch issues on average, with sharper central detail than typical Charlotte or Dahlonega production. Survival estimates suggest perhaps 600 to 900 examples across all grades, a population that supports active collecting without the extreme scarcity of the southern branches. The 1846-O frequently functions as the entry point for collectors building New Orleans quarter eagle date sets. See the full Liberty Head Quarter Eagle series history.
