ELLWOOD CITY, Pa. — Holy collectibles, Batman!

A near-mint copy of Detective Comics 27, a pre-World War II comic featuring Batman's debut, was recently found in an attic and sold to a local collector.

The comic is considered to be the second-most valuable available and can fetch up to $500,000. The only comic considered more valuable is Action Comics 1, where Superman makes his first appearance.

Collector Todd McDevitt said the Batman issue he bought is worth about $250,000, but he won't say how much he paid for it or who sold the book to him.

"It was a typical story of someone cleaning up junk in their attic and finding an old comic book and wondering if this was one of those ones that was worth a lot of money," McDevitt told the Beaver County Times.
