I recently came across this T205 A.A. Mattern with a Hassan 649 back. It is miscut on the left to show what at first glance looked like a print defect - a white strip with the gold missing - and some scuffing on the edge where the gold came back.
Looking closer, some of the gaps on that border aren't from scuffing. In fact, the left border of this Mattern matches the right border of the Newark minor leaguers. This Mattern shared a sheet with at least one of the Newark players. (Click image to enlarge.)
There are subtle differences in the borders of the Newark cards. It can be hard to tell because registration issues can cause the gold, yellow, or black to shift a bit. But I believe that the card to the left of Mattern here is Cady, because that's the Newark card I usually see with a small spur of black jutting off of the top of the black border line (the one that extends from about midway up that border to the bottom of the card).
This is the first miscut T205 that I've seen which shows parts of both a National League card and a Minor League card on the same sheet. (I have not seen an American Leaguer next to a Minor Leaguer on a miscut card.)
If anyone has any T205 miscuts that show a sliver of some non-ML card next to a MLer, or any other neat combinations, I'd love to see them!
