Help Me With My Problem

The Japanese Cool Porygon came out in the first Promo CD from Japan along with 9 other Promo cards, including a Charizard, Venusaur, and Blastoise.  The entire set can be bought for anywhere from $60 - $90 usually.  The Japanese Cool Porygon usually books for anywhere from $8 - $11, maybe a little higher or lower dependant on the area.
