Steve, does this mean same sheet, but different backs
or different sheets?
Nice catch! That would be a small difference between backs on the same sheet. I've seen it shown before, but haven't studied it much at all. So different positions on the sheet. The ones that are the same might be the same position on a different sheet.

It also means that the factory line wasn't part of the overall back, but was added individually. It's probably true for all the SC cards and Piedmont 350-460 cards. I'm not sure about others. It seems like a lot of extra work if you know a brand is only from one factory, but maybe.


Finding out how many slightly different backs there are for the same front and matching them with similar slight differences on the fronts should eventually give us an idea of how many cards the sheet was vertically. Sort of like the plate scratches, but not as obvious, and with no way to tell which one was above another one (Aside from miscuts, but there's too few of those. ) Or if there were two different fronts in the same vertical row and how many of each.
