1852-O $20 (1852-O Double Eagle) NGC AU55. Type 1 Double Eagle. Unlike most double eagles of this date and mint, this Southern branch mint coin shows a bold strike with traces of mint luster in protected areas. On the obverse the centers of the stars show full details as do the reverse design elements. Full dentils are seen on both sides. Only trace of wear is seen on highest points to confirm the grade. The surfaces are original, clean, and, for the grade, free of marks worthy of individual mention.

James Barton Longacre designed the pattern for the double eagle in 1849. It was produced because of the huge amount of gold that came into the Mint from California. With the discovery of gold at Sutters Mill in January 1848, the California gold rush began. It led to an influx of miners and others into the area. The vast quantity of gold produced led to a need for a standard form of exchange. The new denomination was the governments response. They also felt that it would be useful for large commercial transactions and that it would facilitate foreign trade.

Longacres design 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 mint mark is between the tail feathers and the N of TWENTY.

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 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. 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.
