1854-S $20 (1854-S Double Eagle) NGC MS61. Type 1 Double Eagle. Bright mint luster shimmers from the protected areas of this branch mint 1854-S Double Eagle. It strike is full as seen in the centers of the stars, the hair detail on the obverse, and the eagle on the reverse. The surfaces are clean for the grade, and no wear is seen, as expected for a mint state coin. There are a couple of die cracks on each side that add interest to the piece.

James Barton Longacre designed the double eagle. It 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 double eagle 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 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 relive 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.

James Barton Longacre was born in Pennsylvania in 1794. He became an apprentice to a bookseller and then a banknote engraver in Philadelphia. In 1819 he worked on his own as an engraver and made metal plates for bank notes and book illustrations. His works included one on stage personalities and another on the signers of the Declaration of Independence. In 1830 Longacre and James Herring made plans to do a series of biographies of famous men in the military and in politics. This project became the National Portrait Gallery of Distinguished Americans in four volumes that was first published in 1834. This set of books brought great fame to Longacre and those who worked with him. In 1844, through the influence of John C. Calhoun, Longacre was made Chief Engraver at the Mint, where he succeeded the late Christian Gobrecht. Longacres experience was limited, but he was a talented artist. By 1849 he was able to create the gold dollar and double eagle, the design of which lasted until well into the twentieth century. One of Longacres associates, Chief Coiner Franklin Peale, opposed Longacres appointment and became an obstructionist. Peale ran a private medal-making business using Mint facilities, and he felt that Longacres presence would jeopardize it. In 1854 Peale was fired by President Franklin Pearce, and Longacres life became easier. Longacre remained Chief Engraver until his death in 1869. Coins from Longacres estate were auctioned in 1870. They included patterns, coins of Chile, and regularly issued coins.

The year 1854 is the first year of production for the San Francisco Mint, and the double eagle was the coin most in production for the year. They were widely distributed and heavily worn specimens are common today. In its population report, NGC shows 4 in MS61 with 42 better.
