Do they?
I just dug up around 300 cards which a neighbour gave me when he moved away around 98-99 or so. Most of the cards are from the 87-91 era.
The thing is, I don't know shit about cards, let alone what makes cards valuable. Is it the fame of a player that makes a card $$$$, and how do you know if a card is rare? Is there anywhere I could get them valued?
