it's just my personal preference to have books non-pressed. in my opinion there's more $ to be squeezed out of a book if it's pressed which is why it's difficult to find keys non-pressed. people have hard feelings about if pressing is restoration or not, so again, it's just my personal preference to have a non-pressed book. If you dig pressed books, that's cool. No CGC does not notate pressing in any way, shape or form.
While putting my xmen run together I found a large well know online comic store (not MCS) and they had a bunch of xmen books I wanted. I asked if they were pressed and the answer was they press every single book from a 50k book to a 5 dollar book. Some people like how books look pressed, I don't.
I don't want to start a big ugly debate thread about pressing it's just that when it becomes difficult to find any key that's not pressed I just get bummed is all. I have to change my attitude and it bugs.
