Hi all, I'm completely new to all of this. I'm interested in selling my comic "collection." I have over 1000 comics from 1960's and early 1970's, mostly Marvels. According to Overstreet, most of them would be worth $20-$80 if they were graded 6.0. Over 50 of them look to be worth over $100 if graded at 6.0 , and a couple of them over $1000 at 6.0. I don't know how they'd be graded. They've all been in sleeves with backing cardboard for at least 20 years. Where should I go from here? Thanks for any advice anyone has.
