Okay, so I have recently started getting into collecting comic books. I do not have many and have not spent that much on any of them. In fact, right now I only have Spiderman-Return to the mad dog ward FLASH - No.246 Captain America - No.241 Hulk - No. 243 Anyway, I was wondering what older comics are best to pick up for decent prices, and what comics are out current that down the road are going to be a collectors item? Are there any? I could use some help as the ones I have I only bought because the covers look cool. Thanks!
