The 1861 $10 Liberty Gold coin, produced in San Francisco, is part of the Liberty Head series, which was minted from 1838 to 1907. This particular coin features a design with Lady Liberty on the obverse and an eagle on the reverse. The "No Motto" variant indicates that it lacks the inscription "In God We Trust," which was added to later issues. Coins from this period are highly sought after by collectors, especially in well-preserved grades, due to their historical significance and gold content. The San Francisco Mint's production during the Civil War era adds to the coin's appeal and collectibility.
