A Tournament Champion Gold card is extremely rare as it can only be won during a Namco organized competition. It can not be dispensed by AK machine or bought. There is no version number at the back but the front will be written "Battle Tournament Gold Champion".
I am told that it an be sold online for as high as S$150. It may be higher now but most who has it keep it as a trophy. Normally not for sale. There are fakes, of course, so watch out.
Actually my brother got a Great White Shark Gold Champion card and a Gold Case at Genting Tournament last December.Actually, Tournamnet Champion Gold card is considered more rare than Ultra Rares. If you have it, keep it safe. Unless you know someone in Namco Bandai, of course.
