I want to sell my Pokemon cards. How much are they worth?

I have over 700 pokemon cards. About 200 of them are the rare holographic cards. I have a few Japanese cards as well. The rest are just regular cards but they are all in mint condition. I wondering how much they would be worth and if they are even worth my time to try and sell. If i should sell them, where. (Not eBay... I've heard too many bad things about them.)
