Updated answer to question:
An Yovani Gallardo single signed Baseball is worth approximately $55 if it is on a Rawlings Official Major League Baseball and is signed on the "sweet spot".
These values assume that they are all authenticator by a reputable company. An autograph that isn't properly authenticated can be worth as little as half of the value of an authenticated signature.
