What is this spine defect called and how does it affect grade? 1 1

[Washingtonxan]

I know that this is spine wear but what specifically is it called? if it even has a name?

Also would like to know the severity and how grade is affected?

Color seems to be chipped off spine.

Spine Chip - A small piece missing from the area of the spine.

What makes this a more serious defect is when the paper actually chips away and leaves a small hole (or holes) in the spine edge. Even a very small hole in the spine will usually result in a significant downgrade of the book...

In theory, CGC is supposed to grade flaws on the vertex of the spine the same as if they were on the cover. It is obvious the wear on your book is not production, only from wear. I can't see the rest of the book but the spine alone should keep it in the low mid grade area.

Always right on the money, BB. And this is the first time I've ever seen the word "vertex" in a sentence. Yes, Mr. White, SCIENCE!

Thanks for the response. I Just want to clarify this is not my comic, it's available to buy from a comic dealer. Also what is low mid grade is it 4.5, 5.0, 5.5? I have more pictures. There's no other major creases other than the spine, being the major problem.

The book has a lot of problems but it is whole, no pieces missing, and presents well. IMO, 4.5.

I agree.

That's a nicely presenting 4.5/5.0, which would qualify as "low mid-grade", particularly with GA books. 

I think of mid-grade as roughly 4.5 to 7.5 , though I suppose with Bronze to Modern, 4.5 seems somewhat "low grade" and 8.0/8.5 may not seem especially "high grade".
