How much are my pokemon cards worth?

The below link will send you to a great website for selling cards or wondering how much they are worth to that company. Simply click the "Our buylist" in the top right hand corner and goto the Pokemon buylist. Then search for the set of each card, and it will have a buy price that company will buy them from you, you can also search for the card and it will tell you how much that company sells that card for. Thanks. I hope this helps.
