REALLY nice illustration.
Here's my 2 cents (since we have now dedicated four pages to this): the corner post was cracked. I could see the white glare of the shattered plastic in one of those photos. The book looked about right at 8.0, but I didn't like that top right corner impact.
The older cases are a bit different than the current iteration. Many of the top labels peeled off over time, and plenty of the CGC labels got wavy inside the holder.
I would NOT have suggested any shenanigans with that book, but you've already made a decision and returned it. Doesn't matter now.
