Kasumi said:We reckon a complete set of the 10 cards were awarded to each winner as a prize. So there were 10 winners and 10 cards produced making 10 copies of each card. However, it really is just all speculation so there is no real answer. We have not seen anywhere close to that number of cards anyway but it's understandable as these rare prize cards, won't all show up. Not everyone who gets them will sell/trade, I know I wouldn't!
When they print these cards the do it in a run and quote if im wrong but I am sure there 36 cards per sheet so there could be 36 copies each of the hard to find cards PTC or Wizzards could have destroyed the others or kept them at head office there were leaks of some of the hard to find DBZ CCG cards a couple of years ago when score entertainment went bust.
