Discovery Note
Capital Currency, Inc. - June, 2001

Series 1928E $5.00 Legal Tender Mules were known only on the G-A and H-A block, although Mule researcher and collector, Peter Hontoon speculated that the Star Note from this series could have also been printed with Back Plates 637 and/or 629 making it a mule as well.

Currency Dealer, Arri Jacob, is credited for the first discovery of this Mule variety. It has Back Plate # 637 and is currently unique.
