I saw this note on Ebay years ago and was dumbfounded. I saved the scan. This note did sell for $78,000.00.
I have held up to a $5000.00 bill and have a $500.00 and $1000.00 of my own now. I have never seen or held anything like that. The closet I ever came was when they were still encased in the glass in the casino.

What an investment that would have been if you had purchased one.
