Superman comic book breaks record

If you thought $1.075 million was a lot for a comic book, try $1.5 million.

That's how much a Batman and Superman comic sold for, respectively, in two separate auctions this past week.

The copy of the 1938 edition of Action Comics No. 1, featuring Superman's debut, is widely considered to be the Holy Grail of comic books. Though the original sold for a humble 10 cents, the issue now holds the record for highest priced comic book. Online auction site ComicConnect.com hosted the sale Monday. The buyer, a private collector and avid comic book fan, wished to remain anonymous.

A copy of the same issue went for $1 million in February, but the $1.5 million copy was in much better condition.

Just days earlier, a copy of a 1939 comic book featuring Batman's debut sold for $1.075 million at an auction in Dallas.
