1 USD suckaa
the card is worth $20,000. I have a autographed Michael Jordan basketball card
Robin Earl was a professional football player who played in the National Football League. His autographed card is worth $25 as of 2013.
It depends on what card it is. For an example, retired player cards are worth more. An autographed Wayne Gretzky rookie card would be worth much more than an autographed Sidney Crosby rookie card. If you just want a pack from stores they are worth 2-10$. If you're selling at a yard sale maybe 20-50 cards for 1$, yet again depending on the player.
If autographed, an authentic card could be worth 150.00 or more.
it would be worth $300
