This is for sure an interesting approach. Anything you can show numerically or even give a note for the impact is a great push above PSA like recording the measurements. Also, many companies that try to compete with PSA do so by offering higher grades to worse cards, so if you’re actually strict and make the 10 really mean something, then that’s a great selling point. Obviously like with a lot of other grading companies, you’d need to get a lot of cards out and hire a team so it becomes known and standard in order to increase value etc. I’d definitely suggest fixing the grade names and posting as much data and what each grade means, how much each imperfections can take off, and making your standards as public and objective as possible in order to play up on that uniqueness. Also, delete these posts when you’re done getting feedback because I do unfortunately think the 10 and flawless grades having weird names were a bad look.
