Where can I find…Value of Comic books?
I agree with Eli. Another point about signed comic books is the buyer will usually want a certificate of authenticity. Some people will forge signatures in order to get more money. The certificate (from Wizard or other reputable store) vouches for the signature. You can either buy or read from your local book store the Overstreet Comic Book Price Guide. Or on-line, the Comics Price Guide: http://www.comicspriceguide.com/default.… I’m not sure if either of those sources list prices for signed comics.
