Thanks for the input y'all.
It came back a 2.5. The book has no missing pieces or pages, no tape or brittleness anywhere, no staple rust, cover and center page are not loose at all. Raw I gave it a 2.5-3.0. I sent it to get pressed and cleaned hoping for a graded 3.0+ but it seems (to me) that the service to the book actually did more harm.
I included a photo of the book prior to pressing and the spine was in better condition. As for the back cover, I'm unsure how it got those stains all over. It just had a light stain on the right center.
Should I resubmit with CGC or just take the 2.5 grade? I was really hoping for a graded 3.0 or higher.
