An ultra-rare copy of Action Comics No. 1 - which featured the debut of Superman - has smashed comic book sales records by selling for $3.2 million US at auction.
Bidding on eBay for the 1938 comic book started at $1,600,100 in mid-August. Hours before the virtual sale closed on Sunday, a flurry of bidding drove the price tag up to $3.2 million
, which shattered the previous record for most expensive comic book ever sold when another copy of Action Comics No. 1 (a copy that reportedly belonged to Hollywood star Nicholas Cage) sold for $2,161,100 in 2011.
This particular copy of Action Comics No. 1 was issued a 9.0 grade by rating company Certified Guaranty Company for its excellent condition, making it one of the finest copies in existence.
"The book looks and feels like it just came off the news stand," said Paul Litch, the company's primary grader. "It is supple, the colors are deep and rich and the quality of the white pages is amazing for a comic that is 76 years old."
