First of all, I'm only interested in trading for Tony Parker (preferably numbered) cards right now.
I asked in these forums once before, and was told that this dent in the bottom left corner should take anywhere from 10-50% off the value of the card. I personally was thinking maybe 25%, so I decided to go with a minimum of 25% and a maximum of 50% off. This card books at $40, so I'm looking to get $20-30 BV in return.
Let me know what you'd be willing to give up in return for this card. Thanks!
Also, if you'd like to see another scan of the card let me know what you'd like to see and I'll get it for you.
