The Liberty Head eagle, designed by Christian Gobrecht, shows a profile of Liberty facing left wearing a LIBERTY inscribed coronet with her hair tied in the back in beads. Two long curls hang down her neck, one in the back and the other on the side. She is surrounded with thirteen six-pointed stars. The date is below the truncation, which shows no drapery. The motif is taken from a Benjamin West painting of Venus. It was also used with modifications for the Large Cents of 1839. The reverse shows a heraldic eagle with outstretched wing looking to the left. On its chest is the Union shield. In its talons it holds the olive branch and arrows. The error in the previous issue, Scots eagle held the arrows and the olive branches in the wrong talons, is corrected. Except for being interrupted by the tips of the eagles wings UNITED STATES OF AMERICA surrounds the reverse, separated from the denomination TEN D. by dots. Dentils are near the edge on both sides of the coin, and the edge is reeded.
The Type 2 Liberty Head Eagle, Motto Added was created when the motto IN GOD WE TRUST was added to a banner designed by James B. Longacre above the eagle in 1866. The change was made in response to pressure organized by the Reverend M.R. Watkinson. The motto remained until 1907, when President Theodore Roosevelt told Augustus Saint-Gaudens to omit it on the newly designed eagle.

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.

The 1893-S eagle is a condition rarity. At PCGS and NGC only 7 have been graded finer than the current piece, and these numbers do not account for crossovers and resubmissions.
