Transformers Retailer-how does this affect grade

[Eternal]

I was wondering if you could help on this issue. This is definatly not a huge $$$$ book, but i have a couple of books that have this type of bo bo, and wonder how it affects grade. If you look at the bottom right corner you can see an impact mark that looks like it hit the ground on the corner and goes all the way through the book to the back. Could you tell me what this book would have received if this was not there and what it would get now that it is there. Thank you.

This is a tough call from a scan, it is hard to see how severe it is. Typically this would put a modern book in the 8.5 to 9.0 range.
