1856 $20 SSCA (1856 Double Eagle SS Central America) PCGS Genuine. This boldly struck 1856 Double Eagle from the S.S. Central America shows bright mint luster on its devices. The strong strike, especially on the reverse, allows the viewer to fully appreciate Longacres design. Elements that are often weakly struck, the lines of the shield, the eagles feathers, and the words of the motto are all easy to see. The coin has sufficient detail to grade in the AU category. A considerable amount of mint luster remains within its devices.

James Barton Longacre designed the double eagle. The obverse 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 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 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).

It is interesting to note that until the discovery of the shipwrecked S.S. Central America, 1850s double eagles in gem 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 and gold bars, nuggets, dust, and 5200 newly minted San Francisco gold coins. The loss of the Central America triggered the Panic of 1857, which was actually caused by bank instability and generally poor economic conditions.

In 1985, the Columbus-America Discovery Group raised ten million dollars and began to search for the wreck. They found it at a depth of 8,500 feet off the coast of South Carolina. It is estimated that the total coins, ingots, and gold bars were worth more than one hundred million dollars.
