4. Action Comic No.1
Made by Joe Schuster and Jerry Siegal, the first superhero comic would have cost around $0.10 dollars to buy in the store. This first comic book features several different superheroes, including Superman, and it is credited as starting the trend for superheroes.
If you can find one of these first-ever comics, you’re sitting on $3.2 million! It’s worth checking through any old comic collections to see if you have one!
This originally came out in 1938. On its cover, there is superman lifting up a car with people fleeing. The first issue had 200,000 copies printed, and these sold at a considerable speed.
Soon after, the comics were selling around one million copies every month!
