How many times have we read this story..?
When I first started, I thought that most comics I buy off-the-shelf would just naturally be a 9.8. Do you know how rare that actually is? They're probably 8.5s-9.2s when you buy 'em. I have no problems with this. When you get an actual 9.8, you begin to realize how much small imperfections can rack up to a lower grade.
My coworker recently gifted me some comics he used for drawing-detail purposes. Bought 'em in 1990, bagged and boarded them, and didn't really stress the books out. There's no way any of them are even 8.0s. They're not beat up but they aren't close to mint.
Nobody's perfect, and that includes CGC, but they have a good reputation and I rarely, very rarely, disagree with grades they've (metaphorically) stamped on their slabs.
