Yea if even one human being on planet earth is willing to pay more for a certin card then you are then the card has more value then what you believe. What buyers are willing to pay determines the value of a card. Not what someone thinks its worth. I mean look at it this way. If you are willing to pay $20 for a card I have and ND3 is willing to pay $40 then how exactly is my card only worth $20?
If you give Panini business you deserve what you get
