NEW YORK (CNNMoney.com) -- There's a multi-million-dollar battle brewing between superheroes.
Just a month after a Batman comic knocked Superman from his perch as the highest-selling comic book ever, Clark Kent's alias is back for revenge. A high-quality copy of Action Comics #1, which marks Superman's 1938 debut, sold for $1.5 million on Monday.
A lower quality copy of Action Comics #1 was the first comic book to reach the $1 million mark in February, but it only held the record for three days before a copy of Detective Comics #27 - the comic book that marked the first appearance of Batman in 1939 - netted $1.08 million at auction.
ComicConnect.com, an online comics seller, claimed to make both the record-breaking $1.5 million sale Monday and the $1 million sale in February. Vincent Zurzolo, who co-owns the site with Stephen Fishler, said headlines about the sales last month helped drive interest in comic book trades since then.
Three million-dollar sales in a month, regardless of the character, are great news for comic book fans looking to increase the value of their collections, said Ed Jaster, vice president of Heritage Auctions, a Dallas-based auction firm that sold the Batman comic book last month.
"This puts the hobby in a much greater light," he said. "People now have to think of vintage comics with the same kind of respect that they would with American paintings."
As for the age-old question of who would win in a fight, Zurzolo said that,- hands down, it's the "Man of Steel."
