1852-O Double Eagle - 1852-O $20 NGC AU DETAILS. This Southern branch mint, well struck 1852-O Double Eagle has a small reverse scratch, which caused the details grade. The coin shows full details in the centers of the stars and the design elements of the reverse, especially the eagle. The surfaces are original, which is attested to by the presence of some copper staining, more so on the reverse, but they are otherwise clean for the grade. Hints of mint luster are found within the devices.

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.

Designed by James B. Longacre, the coin shows a Liberty head facing left, wearing coronet inscribed LIBERTY. Her hair is tightly tied in the back with two loose curls hanging down her neck to the end of the truncation. She is surrounded by thirteen six-pointed stars with the date below. Dentils are near the edge on both sides of the coin. The reverse shows a heraldic eagle with elaborate ribbons on both sides of the shield extending from the top corner down to the eagles tail feathers. The ribbons are inscribed, on the left E PLURIBUS and UNUM on the right. The ribbons were added to the design to symbolize the denomination since this was the first twenty dollar coin. There is an oval of thirteen stars above the eagles head and an arc of rays from wing tip to wing tip behind the upper half of the oval. UNITED STATES OF AMERICA is in an arc above the eagle, and the denomination TWENTY D. is below. The mintmark is between the tail feathers and the N of TWENTY.
