1863-S Republic Double Eagle - 1863-S $20 Republic, NGC AU58. Large S variety. This near-Mint State, shipwrecked, Civil War dated, Western Branch mint 1864-S Republic Double Eagle comes with a box and blue tag from NGC showing its provenance. Smoldering mint luster is present in protected areas of both sides of the piece. A slight bit of wear on the highest points keeps this coin from Mint State grade. The surfaces are original and show a few abrasion marks in keeping with the grade, more so on the obverse than the reverse. One small mark is on Libertys cheek and another is above the date. The strike is strong with full details on the centers of the obverse stars and the design details of the reverse.

During the California Gold Rush, the S.S. Republic, then called the Tennessee, was used to transport miners to the shore of Panama and Nicaragua to travel to the California gold fields. For several years the ship was used to carry immigrants to the Unites States from Mexico. When the Civil War began, the ship was docked in New Orleans. She was seized by the Confederates and used as a blockade runner. After the capture of New Orleans by the North, she became the flagship of Admiral Farragut for the end of the Mississippi Campaign. In 1864, she resumed transporting passengers and cargo from New York to New Orleans.

The next year she sank in a hurricane off the coast of Savannah. In 2003, the Odyssey Republic Expedition, after twelve years of searching, discovered and began the recovery of the ships treasure. The cargo had been untouched for 138 years approximately 100 miles off the coast of Georgia. Lost Gold of the Republic, a film produced by National Graphic documents the discovery and recovery. The coins recovered from the S.S. Republic are labeled as such by NGC and its affiliate NCS not only to note the historic significance of the coins, but also to indicate that these coins have been professionally conserved. The blue NGC tag was used exclusively for coins from the Republic.

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.

Longacres double eagle design was a new concept that endured well past the turn of the century. When Longacre first 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. In the end Peale was found out and fired in 1854. 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.
