Superman’s First Comic Found in Attic Sells for Record $9 Million

A preserved copy of the first-ever Superman comic was found in a dusty attic and later fetched a record-breaking price at auction.

A rare copy of Action Comics #1, the comic that first introduced Superman, has sold for an unbelievable $9 million, setting a new world record as the most expensive comic book ever.

The comic was discovered unexpectedly in an attic, where it had remained untouched for decades. Experts described its condition as “exceptionally preserved,” a key reason behind the historic auction price.
