1858-S Double Eagle - 1858-S $20 NGC MS61. This Mint State, Western branch mint 1858-S Double Eagle is tied for second finest known at both NGC and PCGS. The coin has attractive, satiny mint luster and is well struck. There are full details on the centers of the stars, Libertys hair, and the design details of the reverse, especially the eagle. The surfaces are original and clean for the grade with no individually notable abrasion marks. There are a couple of copper spots on the reverse mentioned for the sake of accuracy.

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.
James B. Longacre designed the double eagle. He was born in Pennsylvania in 1794. When he finished his apprenticeship in Philadelphia as a bookseller and a banknote engraver, he worked on his own as an engraver of book illustrations and bank notes. His works included one on the signers of the Declaration of Independence and another on stage personalities.

In 1830, Longacre began a series of biographies of famous men in the military and the political arena. In 1834 the result of this series became the National Portrait Gallery of Distinguished Americans that was published in four volumes. Longacre and those who worked with him became famous because of this work. In 1844 Longacre came to work at the Mint. He was opposed by Franklin Peale, the Chief Coiner. Peale was probably responsible for some blundered dies that Longacre was criticized for making.

Peal was involved in a private, illegal medal manufacturing business using Mint facilities. He was concerned that this new political appointee would interfere with his business, and he resisted Longacres appointment as Chief Engraver. Finally in 1854, Peale was fired by President Franklin Pearce. Longacre flourished in his position and 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. 

The 1858-S double eagle is usually seen low grades and heavily abraded because it saw considerable commercial use. Since few were saved, Mint State examples are rare. In its population report, NGC shows 13 others at the MS61 level.
