It's good the book arrived, because you took tremendous risk going outside ebay.
But how is that book a 9.0+?
No idea, I haven't gone in depth with the grading process. To me I would say its around a 8.5. But I will not or cannot say anything for sure. I am not good at that kind of thing. Do I think it's worth the price I paid....well, depends on how rare these actually turn out to be. If these 3 plus the other few I know of turn out to be the only ones, well its totally worth it. If all the other 99 show up...then no, I want a better copy
You tell me
With migrating rust and all the damage you can see, that is a 6.0-6.5
