What is a baseball worth signed by all the actors from the movie Major League filmed in Milwaukee?

My mom has a baseball signed by all the actors in the movie Major League made in the late 1980's. With some actors such as Tom Berenger, Charlie Sheen, Wesley Snipes, Dennis Haysbert, and Steve Yeager.|||hard to estimate





the autographed posters sell for $60 to $100





none of stars autographs are rare or hard to find





so it would depend on how many other balls they have out their that are similar and how many of the cast members signed it.





the provenance is also important, like where did she get it? was it gift or did she win a contest etc..
