Thanks for the reply, guys! I learned the treasury made such note for gold transactions, made a few, and wasn't intended for public use. That's why I was curious to see the 100K note, on how the guy got a hold of one because like you guys said, it could be of ultra-rarity, or a fake, and I really don't know how to tell, but on the illegal part, I don't want to be tangled up with something like that. About the pictures, I'll download them in a couple of days or so if needed, shot it with old school camera (film), A00000417A/serial number.
