That is a sweet copy of SC #22. Looking at the damage on the front and back cover (looks like there is a chip out of the tip of the top left corner on the back), I would put it in the 6.0 range provided there are no other spots/stains (there is one in the L in "Lantern").
I'm confused. If you're looking at the same #22 that I'm looking at, it's > 6.0 !!!
Don't get me wrong - structurally it is a very sweet book but I would say 6.0, maybe 6.5, when you take the defects into account. Here is what I notice in the scan (remember, it does not show NCB bends/creases):
- the corner chip on the back cover should drop it to an 8.0/8.5 to start with.
- small chip middle of top edge back cover
- a few tiny edge tears/nicks along top of back cover (?)
- looks like there is also an edge bend along the left side of the top edge on the back cover (next to the chip)
- light soiling and possible perimeter tanning on the back cover
- multiple spine creases
- light corner crease top right front cover
- appears to be a light impact ding and bend bottom left corner/bottom of spine.
- small stain in L of title (which CGC is hammering right now, along with dust shadows)
- I am also considering the fact that the scans will not show NCB bends/light creases that could be on the book as well.
Since it is a big key, I guess it could be get a bump depending on how CGC feels that day (this would be a given if it were a Marvel), but I would give it a 6.0, maybe 6.5, based on what I can see.
