14. Comic books

Comic books may not be toys in the traditional sense, but this form of entertainment media can also hold significant value.

Even though these objects can be readily found in any thrift store, vintage comic books featuring popular superheroes like Spider-Man, Superman, and Batman are typically highly valuable.

The price of a comic book is determined by its condition, of course, but also by its rarity. The rarest and most valuable comic book, according to Sell My Comics, is ‘Amazing Fantasy #15,’ currently valued at $3.6 million.

You can discover the value of your comics on their website.
