Action Comics #1 (June 1938) is the first issue of the original run of the
comic book series
Action Comics. It features the
first appearance of several comic book heroes—most notably the
Jerry Siegel and
Joe Shuster creation,
Superman. For this reason it is widely considered both the beginning of the
superhero genre and the most valuable comic book of all time. On August 24, 2014, a copy graded 9.0 by
CGC was sold on
eBay for US$3,207,852. It is the only comic to have sold for more than $3 million for a single original copy.
Action Comics would go on to run for 904 numbered issues (plus additional out-of-sequence special issues) before it ended in the fall of 2011.
