Pretty certain there is only 27 and Dan's book only has 27 listed. pricing varies on these cards depending on player, i have seen individual cards sell between $7 (jason moodie) to $20 (Nathan Hindmarsh). As for lots of cards I have seen them sell quite high at $150 for 20 cards and then others lower around $70. Just depends who is chasing them at the time and what they are willing to pay
