Cool note @Jersey magic man. I’ve always been told a portion of an adjacent note should be visible in one of the margins to be considered an alignment error. This one doesn’t fit that theory. Still a cool replacement note.
I guess it qualifies as an alignment error because the overprint is sitting on top of the second printing (the “7” on the top right). Who am I to argue with PMG. Whatever you want to call this error, it is a very minor error.
You can see on the reverse the image is tilted slightly. The top right border is thicker and the left top border is thinner. Yes and that 7 is way over onto the design. I remember seeing these bills in circulation in the 1970's. I'm not going to argue with Steve's expertise, but I just thought that a misalignment was worth more, if the next note was slightly visible. It still looks misaligned to me without that.
I am kind of surprised on the 58 grade though most 58,s have allot better centering, some rival 65.s as I would much rather have the 58 as most are better then the 65,s but not really in this case.
