I have some old baseball cards and have no idea what they might be worth. They are:
Nolan Ryan 1992 from Leaf, Inc. #22 of 26
Mark Davis 1991 from Leaf, Inc. #54
Andrew Neal Allanson 1191 Leaf, Inc. #42
Ivan Calderon 1991 Leaf, Inc. #48

You may try pricing your cards on these sites, remember condition means a lot, also even if they have a specific "retail" price, normally if you are selling them to a dealer, he will not pay retial but want them at a discount to afford to sell them.
