Let’s be honest – most of us are unlikely to have a mint condition copy of a rare first edition of a comic lying around at home. But there are plenty of more modern comics that you might have in your collection that are worth a few bucks, as we'll show you. Grading, in comic book terms, refers to the condition of the comic. The higher the grading out of 10, the better the condition, and therefore the more valuable the comics are.
