Old comic books

So, I went to my grandmas last weekend. She's getting old so she was giving me alot of here things that she has been hoarding for years. She told me that I can sell the stuff or hold on to them. Alot of the stuff is glassware and the such, but she gave me 6 GIANT boxes of old comic books, most from the 60's and some from the early 70's. She told me that she used to go to garage sales and buy them all there and put them in a closet(she liked the art work). So now I have a small collection. I stopped at a comic book store and bought a price guide for them, WOW I THOUGHT MOPARS WERE EXPENSIVE. I already sold one to the guy that worked there for $700.

Now I dont know what I should do. should I sell them all or hold on to them and hope that they are worth more later.........
