I remember it being on a comic shop wall for $20, but who knows, the early 90s were wacky.
as for being sought after...I had always been abe to sell it for 2X guide or so, as guide was just a few bucks. which, for a 1980s non-key, was pretty good. but i probably have not tried to sell one for 2-3 years. people buy it as evidenced by completed sales and it is better than a $2 book. i just figured in this era of hysteria where so many books are $15-20, regardless of having healthy print-runs, that it would have crept up there. I will keep on buying it when I see it, but I am just surprised slabbed SS books do not do better and that nice raw copies are not consistently double digits, but I guess nobody cares about appearances, but they do care about iconic covers?
