For some of my covers, I've been getting slabbed copies. Usually 9.8s. Some are 9.6s.
Also, I have a few lower grade slabs even though I don't have any art from that issue. I just felt like it, they have nice covers. One of them is a 9.8 that looks like it was pressed, hard to hide that on covers with a lot of black.
I don't plan on doing this for very much longer. I keep them lying flat in a file box and it's filled up (about 15 slabs). One more box and that is most likely the end.
Overall, I don't care about SS or pedigrees. But some are pedigrees.
