A couple of years ago, this lady working at a corner store got a Bird series $5 with major errors on it. Some customer got it out of an ATM and spent it there. The note "was" in UNC when she got it, but after like a million people handled it, the note was EF+. When she first got it, she thought it was a fake and handed it over to the R.C.M.P. who later returned it, then she showed a bunch of people at her store, co-workers, customers. She just stores it in a plastic bag, not even a note holder. I offered her $150 for it, but she was going to try and get a higher price on Ebay. She still claimed the note was UNC after all the handling.
But the note was printed off center, major misscut, part of the next note was showing on one side. And the litho and itaglio printing passes didn't match up, they were way out of register and I think the serial numbers where shifted too, but I can't quite remember, either printed too high or too low.
