If you taken them to the shop you might make a huge lost. I say this because you may not know the full valuation of the comic but the shop ppl will. For eg, a particular issue that a character dies, the value can be extraordinary. It could be enough for you to get a lens sometimes if you are really really lucky.
what i suggest you do is that you list down the issues that you have and would like to sell, send them to me and i will check out the prices for you. I collect comics and i have some magazines that include the valuation prices of the comics. it will take some searching, but you never know how much you can profit from the sale.
the other option is that you post on Yahoo Auctions.
To sell them at the shops you would loose out. the other option is to exchange - comics for toys, comics for film...hahahaha
