Wow, three A's fans on one Board!
The Williams and Jackson's are no good...Fingers, Campy, Bando look OK. In fact I think I know the clubhouse boy that signed them - I'll shoot him an email and see if he's willing to confirm.
That basically kills the ball in terms of value, HOWEVER, you've got to of the hardest to find A's autographs on the ball in Gonzalo Marquez and Horacio Pina. Both good. Only worth something to an A's collector, but they are as notoriously cheap as the A's current ownership.
