The very first Hulk comic - which, believe it or not, was called "The Incredible Hulk #1" - is an extremely valuable item to own. First published way back in 1962, it was a comic that described the Hulk as "the strangest man of all time", asked the question of whether he was "man or monster" and depicted him as grey rather than the classic green. A poor condition version of this comic is still worth $800, as long as it is complete and readable, but a completely mint condition version of the comic once sold for no less than $125,000. If you're lucky enough to have a copy of The Incredible Hulk #1, check out the condition of it and consider making yourself some serious cash!
