The only thing prerelease cards from WIzard of the Coast Era are:
Raichu (Base)
Clefable (Jungle)
Aerodacty (Fossil)
Dark Gyarados (Rocket)
Misty's Seadra (Gym)
So I recalled an article that came out a few years ago that talked about the rarest, or most epensive TCG cards in the world. At the time, I thought Pokemon, the TCG in general died away until I read this article.
I was surprised to see Pokemon cards hold so much value, even over MTG and Yugioh. Now, I still don't know much about the card, but is this Pikachu Illustrator really worth that amount?
