Original Pok�mon cards? :D?

I have about 300 of those Tv Animation edition original Pok�mon cards. (Not the trading cards, but the actual original cards) and a bunch of holographic ones, some with the raised crystal/diamond shapes and then a couple of promo ones. I keep seeing sites and stuff that say certain cards, like a first edition charizard card can be like $100, so I'd like to know how much these things are worth. I'm not sure if I'll get rid of them yet, but I am curious.
