About this coinHistory

New Orleans struck 860,000 half dimes in 1851, a significant branch mint output. The 1851-O is a common New Orleans date available in circulated grades at moderate prices. The O mintmark appears on the reverse below the wreath. Strike quality on the 1851-O is generally consistent with other New Orleans issues of the era, which tend to show somewhat softer central detail than Philadelphia coins.
