At the time when comic books first began to be published in the United States, a comic book could be purchased for around 10 cents (which is more than 2,000 VND today). However, now, after experiencing around 8 decades, the prices of these comic books have skyrocketed, rivaling even the prices of prestigious luxury goods.

The comic book that we’re referring to here is the first issue of Action Comics, which was released in 1938 and features the iconic character Superman. This book is considered the first comic book to portray the superhero genre in American comic book history.
This comic book is recognized as a key work of high value in the collection world, as it introduced to global audiences the iconic character, the most famous figure in superhero comics – Superman.

The emergence of this comic book series is regarded as the starting point for the golden age of superhero comics and has developed significantly from then until now.
Notably, the original copy from that era remains in pristine condition since its publication and has yet to undergo any significant restoration. In 1990, this comic was sold for 20,000 British pounds (approximately 600 million VND), and currently, at a recent auction in Dallas, Texas, experts estimate that its value could reach over 500,000 British pounds.

Thus, with the current price in mind, the first issue of Action Comics featuring Superman is considered one of the most valuable comic books in the world.
