Today was a big day in history, at least for super heroes. Back on June 1, 1938, Superman appeared in the first issue of Action Comics  And the rest, they say, is history.

According to the New York Post, last year a copy of that comic book sold for $3.2 million, the highest price ever paid for a comic book.

The 1938 issue was labeled as having “perfect white pages” and given a condition rating of 9.0 by the comic grading service Certified Guaranty Company (CGC).

No other copies of Action Comics #1 have been graded higher and only one other has ever received a 9.0, according to it’s eBay description.

There are only around 50-100 original copies believed to still be in existence.

The multimillion-dollar issue topped another Action Comics #1, previously owned by actor and avid Superman fan Nicolas Cage, which sold in 2011 for $2.16 million.
