Here are a few places that you could look to compare prices and just get a general feel for the market:-)
I dont know if you live in the US or UK but there are plenty of online comic shops. Ebay is also a good place it will give you an idea of what they are realy going for (normaly a third of book value) Conan is not as popular as it was a few years ago (I collect them) but I think that SS will go up in value after all they are turning many of the comic book heros into movies now.
Loved the Freak bros, collect Batman, Shi, Conan, Kull, Robin, Huntress, Warlord, Dracula the best one that I own is a Spiderman signed by Stan Lee that for me is priceless. Ah what the hell lets just admit I love comics (ref to thread on adulthood) I'm still a child at heart LoL
I collect comics, Hockey/Baseball cards, Non sport trading card, Minature soldiers and autographs.
Enjoy them while you still can :-)
