While not new, that's a far better scan of Sullivan than I've found. I have a poor scan of one graded Auth with the same scratch but not showing the crop mark, which was probably trimmed off on that one.
Better scans help, since I'm also looking at the fronts. Each front has a few minor differences that match a particular back. Like having the little registration marks or not.
It's a very long term project on most cards, but a few of the tough ones have specifically identifiable fronts that always match particular back flaws.
