CardExcalibur Wrote:Would you be able to help me come to the understanding of what " SP " means when it comes to looking the card up and how you can tell it's a SP. Example...2006 topps cracker jack, a card will be worth maybe a dollar, but when looking it up, it has beside it a " SP " and then it was worth four times as much. Can anyone help me out with understanding this? Thanks alot.
