Don't sell! I still miss my Sgt. Rock books... All I did was trade those for John Byrne X-Men back in 1984 (meaning I did the trade back in 1984 when I was 13 years old). Buying the books off the old spinner racks... then trading them away for cool but very common books... ugh! It's only been 36 years... I'm almost over it.
Best of luck with the sales!
