Isn't that always the way. The things society once mocked countless nerds and geeks for hoarding becomes exactly what makes them rich.

In this case, it isn't anything as abstract as an idea for an electronic company that will change the interface of communication. What we're talking about here is a near-mint copy of Superman's first appearance in Action Comics.

The first Superman comic, long rumoured to have once been the property of an actor who played the hero himself, just became the most expensive comic book in the world.

Published in 1938, the comic book is in pristine condition, surely a factor in the $2.16 million price tag. The auction and consignment shop, ComicConnect, confirmed the sale Wednesday.

The comic book itself has a fascinating story. Once sold for $86,000 in 1992, then again in 1997, it was owned by the actor Nicolas Cage. Cage was also set to play Superman in a version by Tim Burton in the 1990s but Warner Brothers ultimately decided not to go through with the project.

Meanwhile, the comic book was reportedly stolen from Cage's estate only to be found a decade later in a storage locker, ABC News reported.

The sale beats out the previous record holder; same issue number, different copy. That copy sold for $1.5 million last year. Looks like comic books do appreciate in value (so long as they're in perfect condition, that is) and it would be a wise move to hold on to and invest in these objects of pop culture.

Vincent Zurzolo of ComicConnect and Metropolis refused to disclose the identity of the buyer. Zurzolo stated that it wouldn't be appropriate as the company maintains a confidential relationship with their customers.
