How much to ask for a large Ball card lot?

I inherited a large amount of ball cards from a friend who ped away a while back. Im not really into sports (im a chick ha ha) . I went through and counted all these and there are a lil over 1100 cards here, Id estimate about 50% are baseball 40% are basketball and the other 10% are hockey and football. a big portion baseball cards are from 90-91,91-92. there are a few from the late 80's. the basketball cards range from 90' all the way to around 02'. i know there's a kobe bryan rookie card in there, a troy aikman player of the year card,joe montana rookie flashback card,jose conseco, charles barkley,rodger clemens,dennis rodman, Allen Iverson Floor general card in case., can anyone give me any idea of what i should ask for these cards? btw there are in very good shape with the exception of maybe 5 or 6 cards.
