I'm not a paper money person. Was wondering the typical stuff, is this a legit error, if so what is it called, and does it have value over face. My computer won't currently let me crop photos so sorry.
@paddyman98 has it right, it's a gutter fold. Seems to me the 60's, 70's and 80's had the most error notes by the BEP.
If I recall correctly. I believe US Currency is printed back first and then front. So conceivably the back was printed, then the paper was somehow folded and then the front was printed. This would leave a gutter fold on the front and not the back.
