1857-S Double Eagle SS Central America - 1857-S $20.00 S.S. Central America, Spiked Shield, PCGS MS63 CAC. This fully lustrous, Western Branch Mint, Mint State 1857-S Double Eagle comes with the provenance of the ill-fated S.S. Central America. Just a few abrasion marks on Libertys cheek keep this flashy piece from a higher Mint State grade. The strike is excellent with full details on the centers of the stars and the design details of the reverse, especially the eagle. The CAC sticker indicates that the coin is a premium quality piece that fully deserves the assigned grade.

The San Francisco Mint opened in 1854 because of the need to coin gold resulting from the California Gold Rush. In the West there was an abundance of gold bullion, nuggets and dust; however, there was also an acute shortage of circulating coinage. Congress authorized this mint to relieve the shortage and coin silver and gold and because transportation of bullion to Philadelphia was time consuming and hazardous. Because of its proximity to the Gold Rush area, San Francisco was chosen as the site of the new mint. In 1874 it moved into a new building called the Old United States Mint or the Granite Lady. It is one of the few structures that survived the earthquake of 1906. It remained in service as a mint until 1938, when the present facility opened.

In its first year of operation the Mint made four million dollars in gold coins from bullion. The second building, the Old United States Mint, was designed by Alfred B. Mullett in Greek Revival style. It was built in an E-shape with a central pediment portico. There was a completely enclosed courtyard that had a well. It was these features that saved it in the fire that resulted from the earthquake of 1906. The building was situated on a concrete and granite foundation that was made to prevent tunneling into its vaults. In 1906 there was $300 million, a third of the United States gold reserves, in its vaults. Frank Leach and his men worked heroically to successfully preserve the building and the bullion. The mint was able to resume service and operated until 1937. It was designated a National Historic Landmark in 1961.

Since most of the building was made of sandstone, the nickname of The Granite Lady is a misnomer. Only the basement was made from granite. It was opened to visitors in 1993 and sold to the City of San Francisco for one dollar in 2003 for use as the Museum of the City of San Francisco.

In 1844 James B. Longacre was appointed Mint Engraver through the influence of Senator John C. Calhoun of South Carolina. After overcoming opposition by the Chief Coiner, Franklin Peale, who was fearful that the new Engraver would interfere with his illegal medal manufacturing business using the Mint facilities, Longacre did well. He 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.

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.

There are two different historical views of the cause of the shipwreck of the S.S. Central America. Cedric Ridgely-Nevitt in 1950 said, The foundering can best be laid to the inherent structural weakness of a wooden ship so twisted and torn by wind and sea that some part of the water-tight shell gave way. This view is in contrast to that of Erik Heyl, who wrote in 1953, The chief engineer of the CENTRAL AMERICA turned out to be a thoroughgoing coward. He jumped into the last lifeboat as it was still loading, having only half-a-dozen people in it, and by brandishing a huge knife prevented others from leaving the steamer and getting into the boat.the wreck of the CENTRAL AMERICA is due solely to the cowardice of the chief engineer; when he saw water leaking into the engine and boiler rooms, he just quit cold. Presumably if the chief engineer had kept the engine running, the Captain would have been able to keep the ship afloat.
