The fifth and highest denomination of five uniface India paper proofs from the initial American Bank Note Company Co. printed series. Yellow overprint numerical 10 and guilloche protectors. 27,500 issued notes authorized October 1862. A sharp impression upon the archival paper, but there is some moderate glue foxing seen at the left of the note and bottom corners. Modestly impaired, but from being poorly prepared by the ABNCo. This rare denomination is unpriced in the SCWPM and unconfirmed as an issued note. This is the most important denomination within this early, key set. Extremely Fine Net. From the Eldorado Collection of Colombian Paper Money.
