How much is my signed CD of Taylor Hicks worth?

So, I met Taylor Hicks after seeing him in Broadway's Hairspray. After the show, I bought his CD and had him sign it and got a picture with him. I'm good with the picture of it. But I don't really like his music enough, and since it's signed, it's never some out of the case, which is also signed. So, now I'm wondering how much it's worth, but nothing on the internet has helped with that. Any answers?
