I have a 1996 100 dollar bill that the back picture is printed upside down. I took it to a local store and they put it through there counterfeit machine and it came back real. Anyone know anything about these? I will upload a picture.
Nice find. Errors like this I feel get out more often then the upside down serial numbers because you have to look at both sides to figure it out. I don't know how common this is, but I haven't ever seen one like it. Just out of curiosity, which way is the watermark of Franklin facing? Does it go with the front or the back of the bill?
I am sure the error specialists will chime in soon. In the mean time, don't spend it. :)
