Until the discovery of the SS Central America, 1850s double eagles in mint condition were virtually unavailable. The ship, originally called the S.S. George Law, was a United States mail steamship. In 1857 it sank off the coast of the Carolinas because of a huge hurricane. It was a three-mast, side-wheel steamship that traveled between Panama and New York. The journey took approximately 21 days. In the five years prior to its sinking, it has been estimated that the Central America carried about $150 million worth of gold or one-third of all of the gold mined in California. The ship was 272 feet long and had 578 passengers and crew on board. It also had on board over 35,000 pieces of mail, gold bars, nuggets, dust, and 5,200 newly minted San Francisco gold coins from the West, of which the present coin is one. The loss of the Central America triggered the Panic of 1857, which was caused by bank instability and generally poor economic conditions.

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 mintmark is between the tail feathers and the N of TWENTY.

The Bold 7, Faint S 1857-S Double Eagle is the fifth rarest variety for the issue. As of March 2013, CAC has confirmed 21 in all conditions with 6 in AU58.
