>>57215629A rainbow rare Charizard GX has less than 1k in a PSA 10 pop count. the asking price for such a card is around 2500-3000 dollars.
There may be more of them in the world but I feel that the pricing of such a card is worth it in the long run. since as of now only 822 copies of the card exist in a PSA 10. VS 19k copies of a card "Valued" at 2k.
