Fr. 280m. 1899 $5 Silver Certificate Mule Note. PMG Gem Uncirculated 66 EPQ. John Burke Back Plate #1208. Gem Chief notes are always in demand among collectors, and this example brings bright paper, attractive embossing and a darkly inked design to the table. Depicted at center is Running Antelope, who was Chief of the Hunkpapa in 1851. The portrait incorrectly shows Running Antelope wearing a Pawnee headdress when he should have been a Sioux headdress, although the Sioux headdress which was too tall to add to the engraving.<p>
