How much is the maxx comic book worth?

It really depends... Since the comics are not widely known (which is a shame) and that their only about 15 years old, not a whole lot. However, if you do have the first editions of every single book #1 -35, on eBay they go for over 150 dollars sometimes. So find a big fan, and I'm sure you'll find a decent amount, however it's no Action Comics #1, so don't expect a four figure sum. Cheers.
