My dad has a stupid amount of comics in multiple boxes. He has been lazily seperating them over the past year. But I would say the number would be at least 1,500. He's got pretty much any comic adventure mentioned, ranging from The Golden Age up to the Modern Age. Some of the ones off the top of my head...

X-Men
Fantastic Four
The Incredible Hulk
Silver Surfer
Batman
Superman
Strange Stories (Whatever that comic is called)
Green Lantern
Iron Man
Spiderman
Daredevil
Conan: The Barbarian
Kull The Conqueror
Kull The Destroyer
The Avengers
Captain America
Captain Savage
House of Mystery
Swamp Thing
Star Wars
Star Trek
Dr. Strange
Flash
and many more!

Anywho, I thought I'd put this on here for the comic lovers to see what offers we can get.
