The symbol on the back of the U.S. dollar bill is the Great Seal of the United States. The face (obverse) of the Great Seal first appeared on the back of the $20 Gold Certificate, Series 1905. In 1935, both the face and back (reverse) of the seal appeared for the first time on paper money on $1 Silver Certificates.
