old 500 U.S. banknote for sale in Atlanta, Georgia For Sale

My father passed away and he left some documents in his personal office vault. My wife and I are in Europe for the cremation of his remains. He lived here for the last 15 years of his life.
Included in his personal documents was an old U.S. banknote. This is a $500-bill, still in good condition, but I doubt if it is still legal tender. Suitable as collector's item.
Anyone interested, we are selling it for face value ($500). Fedex shipping is included.
Pictures of front and back of bill is shown on this ad. The red band is there to protect the picture from being used by others without my permission or authorization. Anyone interested in buying the banknote can contact me and I will email a high-resolution picture of the front and back WITHOUT the red band.
Timewasters not welcome. READ AD COMPLETELY BEFORE RESPONDING:
