Most of my opinions are very unpopular I am sure.
I don't get the obsession with grades, to me it's just people trying to feel better than each other by having some stupid competition with made up grading scales.
I think mint, perfect comics are boring. I like loved, used, beat up comics. I love names and stamps on covers and seeing it was used and seeing the history of the comic. I just got a comic that's got lipstick on the pages like some girl was using it to get excess lipstick off, like "biting" down on the pages. I just find the history of an object fascinating and interesting and with a mint comic its nothing and pretty boring, it probably was just sitting in a closet for decades unloved and not used like it was supposed to be.
I hate restoration on comics, or anything for that matter, it erases the history of the object and it's all for money or wanting some perfect comic to feel better about themselves having it in better condition than someone else.
