In April of this year, an anonymous buyer purchased a copy of Action Comics #1 for $3,250,000 USD — the highest figure on record for a vintage comic book. Published in 1938 and featuring the first-ever appearance of Superman, the comic is one of the last known copies in existence. Prior to the auction, it was graded by the Certified Guaranty Company, or CGC, using a 10-point system, where it received a near-perfect score. Any legitimate copy of Action Comics #1 would have been worth a decent sum of money, but this particular book out-sold all others because its physical quality remained superb.
