This is a counterfeit of a rare $20.00, National Currency bill. It was drawn on the National Bank of Commerce in New York, New York. The number of the billnis 66333. There is a reverse repair. The date appears to be Jan. 19, 1801. The bill is in low condition having been circulated for quite some time. There is a signature on the reverse with the date of Oct. 2. I can only make out a few letters.
I did say appears. It's faded on the bill and due to the overall poor condition it's difficult to read.
