1851 Double Eagle - 1851 $20 PCGS XF40. This circulated 1851 Double Eagle is well struck with full details seen on the centers of the obverse stars and the design details of the reverse. The grade of XF40 is confirmed by the rounded prongs on Libertys coronet and the remaining detail in Libertys hair. Traces of mint luster are seen within protected areas of both sides of the coin.

James Barton Longacre designed the pattern for the twenty dollar 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 double eagle was the governments response. They also felt that the new denomination would be useful for large commercial transactions and that it would facilitate foreign trade.

Longacres design for the double eagle 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.
