The note pictured below is just a proof of an authentic note. To date, there are no issued $1,000 national bank notes known to exist. That means that the discovery of an authentic example would be the most important discovery in the world of national bank notes and large size American currency. The note would be valued at seven figures. So if you have one, there is a lot of financial motivation to have the first one to come to light. Needless to say, I would love to hear about it.
