back around 1963 I was a tween who decided to read comics. I started buying all of the Marvel comics - x- men, fantastic 4, sgt Fury, etc. On the first tuesday of the month I would go to the local store and pick up every one. after i got married i still had them sitting in a box 3 feet tall in the basement. I figured why not see if anyone wants to buy them. I ended up selling the whole lot for 25% of book price which was $110. bnasically I got my money back on them. Still kicking myself for selling since of course I had the first issues of most of them.
