maybe 5 bucks. they aren't great games so you cant expect much and most of them are handhelds.
Look the prices up on Ebay or just go and ask one of the dudes that work there. They have an entire database of games and their prices so, i'm sure they'll have it =). Good luck.How much could I get for these games?
