I have an official major league baseball signed by approx. 30 different brewers from the 1980's-almost mint condition,what do you think it is worth?

I have heard that signed/autographed baseballs by many players on one ball don't have as much possible monetary value as those that are signed by just a single player.

If you click on the following searches, it's likely that you will find some signed/autographed cards comparable to yours where you could get a possible idea as to the monetary value of the one that you have.
