1852-O $20 (1852-O Double Eagle) NGC MS61. Type 1 Double Eagle. This rare, New Orleans 1852-O Double Eagle is unusual in that it is well struck. Unlike this coin, the issues of this date are usually seen with weak centers. Lots of mint luster glistens on the devices, and, for the grade, the surfaces are in good condition. Only three percent of the over 500 coins of this date that have been certified are in mint state condition.

James Barton Longacre designed the pattern for the twenty dollar coin 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 double eagle 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 in profile 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 double eagle 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 double eagle was minted in Philadelphia, New Orleans, and San Francisco. In total there were 23,526,676 business strikes. The largest mintage was in 1851 with 2,087,155, and the lowest was 1856-O with 2,250 (not counting the single pattern coin that was struck in 1849).

James Barton Longacre was born in Pennsylvania in 1794. He became an apprentice to a bookseller and then a banknote engraver in Philadelphia. In 1819 he worked on his own as an engraver and made metal plates for bank notes and book illustrations. His works included one on stage personalities and another on the signers of the Declaration of Independence. In 1830 Longacre and James Herring made plans to do a series of biographies of famous men in the military and in politics. This project became the National Portrait Gallery of Distinguished Americans in four volumes that was first published in 1834. This set of books brought great fame to Longacre and those who worked with him.

In 1844, through the influence of John C. Calhoun, Longacre was made Chief Engraver at the Mint, where he succeeded the late Christian Gobrecht. Longacres experience was limited, but he was a talented artist. By 1849 he was able to create the gold dollar and double eagle, the design of which lasted until well into the twentieth century. One of Longacres associates, Chief Coiner Franklin Peale, opposed Longacres appointment and became an obstructionist. Peale ran a lucrative and illicit, private medal-making business using Mint facilities, and he felt that Longacres presence would jeopardize it. In 1854 Peale was fired by President Franklin Pearce, and Longacres life became easier. Longacre remained Chief Engraver until his death in 1869. Coins from Longacres estate were auctioned in 1870. They included patterns, coins of Chile, and regularly issued coins.

In mint state the 1852-O double eagle is an extremely rare coin. In its population report, NGC shows 4 others in MS61 with 5 better. The slightest increase in interest in this date, series, or denomination will cause a spike in the value of this coin.
