1934C $10 Blue Seal Silver Certificate Grades Select AU. This lot is for a $10 Blue Seal Silver Certificate. Series 1934C. This note features the familiar portrait of Alexander Hamilton that was used on all of our $10 bills through 1999, and the back shows the US Treasury. This note does not have the familiar "In God We Trust" motto above the US Treasury, though, as that motto was not added until 1957. The Blue Seal is large and at right; a large blue "10" dominates the left side of the note.
