The bank employee told him they would exchange it for him as it was a good bill. It looks like the left hand upper corner was folded over when it was printed and is blank, with the print on the back in the upper right hand corner. It this a collector’s item?
Yes. You have a “fold over” error note. The paper was accidentally folded over when printed. When you open the fold it is blank underneath. The value depends on what kind of “fold over” error it is (there are ones with extra paper from a miscut sheet) and the size of the fold. For this error, a minimum market value is about $50 and depending on the degree of the error up to about $400.
