Fr. 1180. 1905 $20 Gold Certificate. PCGS Banknote Gem Uncirculated 66 PPQ. These Series of 1905 Gold Certificates have a portrait of George Washington, engraved by Alfred Sealey, and a bright red scalloped Treasury Seal and serial numbers. The field is gold in color and includes a $20 emblem at left. The vibrant tints and overprint featured on this type explain the "Technicolor" nickname, by which these notes are so well known. The back displays the Heraldic Eagle of the Great Seal of the United States at the center and has ornately engraved borders. The entire back design was engraved by Robert Ponickau. Punch through embossing of the serial numbers is readily noticed through the back of the third party holder. The "Technicolor" nickname was applied years later with it being the name of a film process developed in the 1930s.
