Christian Gobrecht designed the Liberty Head eagle. The design shows Liberty facing left in profile wearing a LIBERTY inscribed coronet with her hair tied in the back in beads. Two long curls hang down her neck, one in the back and the other on the side. She is surrounded with thirteen six-pointed stars. The date is below the truncation, which shows no drapery. The motif is taken from a Benjamin West painting of Venus. It was also used with modifications for the Large Cents of 1839. The reverse shows a heraldic eagle with outstretched wing looking to the left. On its chest is the Union shield. In its talons it holds the olive branch and arrows. The error in the previous issue, Scots eagle held the arrows and the olive branches in the wrong talons, is corrected. Except for being interrupted by the tips of the eagles wings UNITED STATES OF AMERICA surrounds the reverse, separated from the denomination TEN D. by dots. Dentils are near the edge on both sides of the coin, and the edge is reeded. The O mintmark is above the EN in TEN.

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.
