When I was in the Navy (back in the late 80's/early 90's), my sister sold a bunch of my comics. The ones I know for a fact, and a bunch I don't know for sure, included Silver Surfer 1 and 8, Capt Marvel 3, Iron Man 1, and some others.
The one that really pissed me off was IMSM 1. That one was in a high grade gorgeous shape. It was definitely a 9.2/9.4 candidate. I bought another copy of it a few years ago, but, it is not even close to the condition of the one that I had. Hell, it wouldn't surprise me if Cal owns it now.
