AND HERE WE HAVE ANOTHER…

Very interesting…
In 2015 Heritage auctioned one of these notes, stating it was, “one of the highlights of the Dorris collection, and perhaps the greatest Proof we have ever sold, as it combines remarkable condition with the utmost in rarity. To our and our consignor’s best knowledge, this $500 Proof is unique, with no others ever being reported or even rumored to exist.” … “If this were a coin, we would easily be discussing a six figure realization, but we have not yet achieved that pinnacle for even the most spectacular and desirable of Obsoletes. Whatever the figure reached this evening, the new owner of this note will have added perhaps the most significant Proof to be offered in 2015 or for many years thereafter.”
