Someone lucky enough to have the scratch paid $317,200 for a rare copy of the first comic book featuring Superman. The issue of Action Comics from 1938 features a cover showing the Man of Steel lifting a car and its original price tag of 10 cents. (There are only about 100 copies known to exist.) The lucky bastard who sold it originally purchased the copy in the '50s at the marked-up price of 35 cents. Decent investment!
