The card is not worth very much right now. I have a KG jr Rookie which is only 50-100 dollars. But hold on to it you never know what will happen.
A lot of money I'd pay ten thousand dollars for it.
I got a mide condition baseball card of him from 1991 and it is card 4 of 10
Several factors influence a card's value. Which manufacturer and which line of cards, how well is it centered, and physical condition as well as the number produced all contribute. There are collectibles value guides- Tuff Stuff and Beckett's are two well known publications. The ultimate valuator is how much an individual is willing to give for a specific item. Not to bring down the excitement level too much, but I have thousands of cards from "back in the day". Several have a bit of value but most are just cardboard with a picture on them. Either way, they don't get any better with wear. A card sleeve is a good idea for a $$$$ card or just a favorite player.
Not a lot. You can buy a baseball book or you can also check on eBay if you type in the card you have. Baseball cards don't go for nearly what they used to. I have a signed Ken Griffrey Ball and Photograph and I can't enough for them to sell them.
