1935G $1 Blue Seal Silver Certificate Grades Choice AU/BU Slider Motto. FR-1616 Smith-Dilon Midway through the final issue of the 1935 series of $1 silver certificates, the now-well-established motto of "In God We Trust" was added to the back of the notes. Thus there are both "With Motto" and "Without Motto" varieties of the 1935G $1 Silver Certificate. Silver Certificates were redeemable in Silver. One of their most distinctive qualities is the blue Treasury seal and serial numbers. These notes include an additional legend printed on the face that is not present on any other Federal Reserve notes. The legend states that Silver had been deposited in the Treasury and was payable on demand to the note’s bearer.
