The market suggests a buck or so, depending on which card and its condition. The rookie card is more valuable by a factor of (maybe) ten, and a signature makes it more valuable, but not by a great sum. Good luck. That is not true!!!!!!!! Not to be mean but it is not worth a buck or so........it can get up to $5,000.(if its signed) If it is in good condition it is worth anywhere from $100 to $1,000.......Thank you.
