1850-O Double Eagle - 1850-O $20 NGC AU55. Type 1 Double Eagle. Here is a Type 1, Southern branch mint, Choice AU, boldly detailed 1850-O Double Eagle. The coin shows subdued mint luster remaining in some protected areas. The strike shows full details on the centers of the stars and the design details of the reverse. The eagle is sharp as are the dentils on both sides of the coin. Light wear is present on the highest points in keeping with the grade. The surfaces are original and clean with no individually distracting abrasion marks worthy of description. 

James B. Longacre designed the double eagle. It 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 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 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.

Longacres double eagle design was a new concept that endured well past the turn of the century. When Longacre first came to work at the Mint, he was opposed by Franklin Peale, the Chief Coiner. Peale was probably responsible for some blundered dies that Longacre was criticized for making. Peal was involved in a private, illegal medal manufacturing business using Mint facilities. He was concerned that this new political appointee would interfere with his business, and he resisted Longacres appointment as Chief Engraver. In the end Peale was found out and fired in 1854. Longacre flourished in his position and was responsible for creating many new designs including the Indian Head cent, the two-cent piece, the Shield nickel, the Liberty Head gold dollar, the Indian Princess gold dollar, the three-dollar gold piece, and the Liberty Head double eagle. 

Only 7 1850-O double eagles have been graded Mint State by both major grading services, and this number does not account for crossovers or resubmissions. In its population report, NGC shows 38 in AU55 condition with 19 better.
