Things You'll Need
Instructions
Assess the condition of your comic book. Back issues - comic books that are not currently on the sales rack - are sold in conditions ranging from New/Mint to Very Poor. Condition determines price.
Refer to "Overstreet Price Guide" and "Wizard Magazine." These guides have definitive listings for each of the different conditions.
Find your title in the listing. If you have a recent, popular book, "Wizard" is the easiest source to use. However, if you have something a little more obscure, then "Overstreet" is your sourcebook.
Price your title according to condition. "Wizard" assumes you have a perfect copy, so you will always get the highest current value. "Overstreet" will list all the prices available.
