Japanese one actually went for 38,000jpy at yahoo auctions a month ago. SO expect an increase in future.
The english one had alot of issues with centering and shit… I think charizard authority sent in like 100 of the blastoise and charizards and none came back 10… all 9s and 8s.
The japanese ones are usually played and damaged, but it is possible to find mint copy… However it probably wont be that cheap after that crazy auction.
