I don't know if I could call myself a collector per se, but I do hoard old PC's, hardware, and software. The closest thing I have to an organized collection is my old Dragon Ball Z action figures, I have a rubbermaid container full of them, all opened though.
I had a holographic charizard that I sold for about $125 back when they were the thing to have, it wasn't first edition otherwise I would have saved it for when I was older.
I had Pokemon cards too! All still in an album somewhere. I remember the hype for a 1st edition Charizard & when they gave out the mew card when you went and saw the first movie
