I mostly collect slabbed horror BRONZE age and mid silver comics-I like verything from horror to off the wall super hero
Spiderman is okay as are the X-Men, but they are not my favorite-I actually see them as over valued right now, where as an issue like The Cat #1 CGC 9.4 iws undervalued, if you understand my logic and reasoning
this thinking seems to work best for me
I do however, love Batman and think those comics in high guide are somewhat reasonable, but are heading up because of Batman Begins...
