One major variety is the 1866-S $10 Liberty Head Gold Eagle with the motto on the reverse. This is the newer design which featured the addition of the motto "IN GOD WE TRUST" on the reverse of the coin above the eagle. This would be the design used in all future years of this coin type. There was also a slightly older "No Motto" variety coin struck in San Francisco in 1866 featuring the older design without the motto.
