When I first got married we lived in a duplex with a shared basement. Kind of moldy down there so I decided to get rid of the three foot high box of Marvel comics from the early 1960's that I had kept. I got 25% of then book value (1973) for almost all of the first edition Fantastic Four, Sgt Fury, Spiderman, etc. and a bunch of Mad Magazines. Total was $110 which I figured is about what I paid for them. Big mistake that I obviouisly still regret!
