1845-O

The 1845-O half eagle marks a steep pullback at the New Orleans Mint, with production falling to roughly 41,000 pieces after the 1844-O run of about 364,600. That is nearly a ninefold drop in a single year, and it shapes everything about how the date survives today. Bullion supply, press allocation, and the demands of silver coinage all pulled against the half eagle queue, and the smaller delivery left a much thinner survival pool when later generations pulled coins from circulation. Most pieces that come to market now wear the marks of long use rather than the looks of vault preservation.

The defining feature is the small O mintmark on the reverse, set just above the denomination and below the eagle's tail. Authentication should start there. Counterfeiters have been known to graft an O onto a more common Philadelphia coin, so the join line, the font weight, and the surface flow around the letter all need close inspection under magnification. A genuine piece should also weigh 8.359 grams within a tight tolerance, and any meaningful shortfall in mass or in specific gravity is a warning sign. Strike softness on the eagle's neck feathers and the upper hair curls is normal for the issue and should not be mistaken for tooling or wear, since New Orleans dies of this period often left those points lightly defined even on fresh strikes.

For collectors, the 1845-O sits in a quiet but real scarcity tier among early New Orleans half eagles. Surviving population estimates run in the low hundreds, with most examples landing in the Fine through Extremely Fine band. About Uncirculated coins draw a clear premium, and Mint State pieces are rare enough that they tend to anchor specialist sets when they appear. Auction prices reflect that pattern, with circulated examples available at modest cost and high grades climbing sharply.
