Hey all, I just acquired this note: What confirmed the error for me, is that the border designed is misformed just to the left of the paper jam on the face, where the paper is straight. I got a great price, considering that I paid the market value of this note if it were without the error. Now this note is position E. I think more modern large notes were printed in sheets of 8 if I'm not mistaken. Can anyone confirm that this was the top note of the sheet?
Yes, some of the later large-size plates were 8-subject, with ABCD down the left column and EFGH down the right. After the back and face intaglio printings, the 8-subject sheets were cut in half vertically so that they could be serialled on the regular 4-subject numbering presses. For a while, the BEP even tried 8-subject plates with the second column inverted, so that the E note would actually be upside-down at the bottom of the sheet. The idea was that it would be impossible to print inverted-back errors this way, since rotating the sheet by 180 degrees between printings would make no difference.... Even with this system, though, the top margin of the E note would be located against the outer selvage of the sheet. I have no idea how to tell whether your note is a printing error vs. post-printing damage, though.
