How much autographed baseball worth?

In 2002 I went to a Detroit Tigers game, and stayed in the same hotel as the visiting Cleveland Indians. I carried a ball around with me and picked up around 10 autographs.. A couple you can't tell the name but there are some notable autographs on it ( CC Sabathia, Jim Thome, Ellis Burks, Milton Bradley). Not that im even looking to get rid of it, but how much would it be worth?
