Dude you're full of shit! Comic books actively sell and go up for auction all the time! And the value has continued to increase with the advent of blockbuster movies and events like comic con based on these Marvel and DC characters generations have grown up with! When the first Spider Man movies came out, my collection tripled in value and I could name my price! I sold one issue with 1st appearance of Doc Octopus in it for over $500! One fuk'in book and it's worth more today!
Don't talks shit because you invested in bullshit worthless ass cardboard! Buy multiple boxes of worthless ball cards just to hopefully find "one" that is worth a shit! It's a fuk'in scam and idiots like you buy right into it! I don't see no studios making movies about Ken Griffy Jr!
Meanwhile, Spider Man, Iron Man, Superman, The Hulk, Fantastic Four, Batman, etc... all big time fuk'in collectables. Get out now douche bag while you still have some pocket change left and invest in comics, I'll even tell you what ones to buy! Go to any comic book/ball cards/collectable store and ask them where they make their fuk'in money! It's aint on no damn ball cards that's for sure!
