If you were to ask me, I'd say you could only get a couple dollars out of it, unfortunately...the bottom's dropped out of the pokemon card market, and unfortunately all the cards that used to be valuable are valueless now, especially ones that aren't good for decks, or not even usable in America at all like the Japanese Rocket's Zapdos. A couple years ago, stuff like Cool Porygon used to be worth $50, now I'm selling all my extra ones at yard sales for $1 (I only have two or three left now I think ._.;; ) You could never get more than $3 for a base Charizard I bet, probably no more than ten for a Shining Gyarados. Pretty much the only thing that's worth anything these days is the rarest of the rare cards, like Prerelease Clefable and the American VS, or super-rare Japanese cards like Pikachu trophy cards or the Tropical Mega Battle trainer...if it's not legendary in its rarity, you'll likely never get more than a dollar for it if it's a holofoil, pennies if it's not.
