1847-O Half Eagle NGC AU50 - 1847-O $5 NGC AU50. Here is an appealing, rare, Southern branch mint 1847-O Half Eagle, original and clean for the grade with no notable abrasion marks or other distractions. The coin is well struck with full details on the centers of the stars, Libertys hair above her ear, and the eagles neck. Unlike many branch mint coins from pre-Civil War days, this one shows dentils that are also well struck. Subdued mint luster remains in some protected areas of both sides of the coin.

Authorized to produce gold and silver, the New Orleans Mint struck quarter eagles and dimes in 1839. It operated from 1838 to 1909. In that time period 427 million silver and gold coins with the O mintmark were coined. By the mid 1850s denominations made in New Orleans included three-cent silver pieces, half-dimes, dimes, quarters, half dollars, silver dollars, gold dollars, quarter eagles, three-dollar pieces, half eagles, eagles, and double eagles. The first deposit was of Mexican dollars which amounted to more than 32,400 dollars. The first coins struck were Liberty Seated dimes. Each year between the beginning of August and the end of November, the mint closed because of the annual outbreak of yellow fever.

During the Civil War the Mint was held by the Confederacy and used to produce its coinage. It was the only mint to produce uniquely identifiable Confederate coinage, the 1861 half dollar with Confederate reverse and the copper-nickel cent of the same year. In 1862 the New Orleans Mint was captured by United States Marines commanded by Commodore David Farragut and closed as a minting facility. The mint reopened as an assay office in 1876. Three years later federal coinage resumed. The New Orleans Mint was the only branch mint in the South to continue coinage after the Civil War. It lasted until 1909 when it was displaced by the mints in Denver and San Francisco. From then until 1931, the New Orleans Mint building was used as an assay office. It was then converted to a prison for Prohibition violators. In 1934 the prison was closed, and the Coast Guard took possession of the building. In 1979 it was transferred to Louisiana to be used as a museum.

Christian Gobrecht designed the 1847-O half eagle. He was the third Chief Engraver at the United States Mint. He was born in Hanover, Pennsylvania in 1785. His father was a German immigrant, and his mother traced her ancestry to the early settlers of Plymouth, Massachusetts. Gobrecht married Mary Hewes in 1818. One of his early positions was as an engraver of clocks in Baltimore. Later he went to Philadelphia where he became a banknote engraver. He invented a machine that allowed one to convert a three-dimensional medal into an illustration.

In 1826 Gobrecht did his first work for the Mint as an assistant to William Kneass. After Kneass suffered a debilitating stroke, Gobrecht did all the die and pattern work for the Mint. He became Chief Engraver in 1840 and served until his death in 1844. He was famous for his Liberty Seated motif, which was used for all denominations of silver coinage including the half-dime, dime, quarter dollar, half dollar and silver dollar. He also designed the Liberty Head gold eagle, a motif that was also used on the half-cent, the cent, the gold quarter eagle, and the gold half eagle. 

The design shows a left facing profile of Liberty wearing a LIBERTY inscribed coronet. Her hair is tied in the back and there are two loose curls that hang down her neck. Around the head are thirteen six-pointed stars, and the date is below the truncation. At the periphery of the coin are dentils. The coin also has a reeded edge. The reverse shows a heraldic eagle similar to the one on the Classic Head half eagle except that the eagle is smaller and its neck is not bent so aggressively. The inscription UNITED STATES OF AMERICA surrounds the eagle, except for its wing tips, in an arc. The denomination is below, separated with dots, and written as FIVE D.

Pre Civil War gold from the New Orleans Mint is rare because of low original mintages and low survival rates. The 1847-O half eagle is no exception. It is the rarest of its denomination from the New Orleans Mint and one of the rarest of the series. Only about 55 are known in all grades. In its population report, NGC shows 5, including the present piece, in AU50, and PCGS has 4 at the same grade level. These numbers do not account for crossovers or resubmissions.
