How much is my '07 LaDainian Tomlinson card worth; it is a topps card and i dont know how to tell if its rare?

Question

it is signed(umm most of the cards are signed anyway). It is a picture of him carrying the ball running(obviously) and is wearing the away jersey

Answer 1

The card itself isn't worth much.  You say it's signed?  Do you mean it's LT's genuine autograph, or is it just part of the manufactured card?  LT's signature is maybe worth something apart from the card.  I don't collect signatures, so I'm not sure what a genuine LT autograph might be worth.
