1855-O Eagle - 1855-O $10 PCGS AU55. This bold, Southern branch mint, Choice About Uncirculated 1855-O Eagle has amazing eye appeal because of its color and luster. The coin is a mixture of light yellow and darker gold with bright mint luster remaining in protected areas of both sides of the coin. The coin is a true slider, with just a trace of wear on its highest points. Aside from a small mark near the eagles head, the surfaces are clean and original, confirmed by the colors and luster. The strike is above average with full details on the centers of about half of the stars, most of Libertys hair, the eagles neck, and the area to the lower left of the eagle. The dentils are full and strong on both sides. 

When Mint Engraver William Kneass was unable to resume his duties after a debilitating stroke, Christian Gobrecht was asked to do his work, which included making a new half eagle that would be uniform with the eagle. The Liberty Head half eagle with no motto was minted from 1839 to 1866.

Gobrechts 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. The mintmark is below the eagle and above the denomination.

Gobrecht became 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 New Orleans Mint was authorized in 1835 by President Andrew Jackson, hero of the battle of New Orleans. The bill that Jackson signed also authorized the mints at Charlotte and Dahlonega. William Strickland, a Philadelphia architect designed all three branch mint buildings. The New Orleans Mint building was made in the solid, bulky Greek Revival style of architecture. It was the largest of the three branch mints and located at major port of entry. Unfortunately Strickland did not account for the soft ground around the site. Because of it, the building had to undergo numerous repairs throughout its history.

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.

The 1855-O Eagle is scarce. Most examples are found in XF condition or worse. All AU examples are rare, and Uncirculated coins are extremely rare. In its population report, PCGS shows 2 1855-O eagles certified at the AU55 grade level with only 3 better.
