I agree that e-bay would be the best option, but if you’re set against it there are a few other sites you can go to. Nostalgiazone.com is a cool site I’ve visited a couple of times. They have some pictures of the guys there and they look like total comic book-geeks (no offense

, I also collect comic books, Marvel as well) so that should give you some confidence. I’m sure if you send them an e-mail they’ll be more than glad to help and maybe make you an offer or two.
Have you thought of putting up your own site or blog and maybe offering them there? That is another idea: you can post pics of your comic books to show they are in mint condition (as done on e-bay) and basically talk about them and stuff. I think a blog would be the best way to go with this.
- One thing I’m not sure of is what restrictions if any Marvel may have concerning the sale and purchase of their comic books online. So that might be something to keep in mind as well.
