‘Avengers’ #1
Truth be told, “Avengers’ #1 is not quite as rare or sought after as many of the other books on this list. It’s still worth a lot of money, though, thanks in large part to featuring the debut appearance of Earth’s Mightiest Heroes. This comic has shot up in value in recent years as Marvel’s movies have brought more popularity to its characters, and a high quality copy of the book sold in 2018 for $250,000.
