What is my old autographed baseball program worth?

Hi, I have a 1968 Red Sox baseball program , autographed on the cover by the manager at the time. The ticket stub is taped in the middle of the program and i have confirmed this was Mickey Mantle's last game. Sept. 28, 1968. Red Sox vs Yankees. I have no clue how to value this because there are several ways to look at it.What is my old autographed baseball program worth?
It's not worth anything because it's not certified.





Dick Williams is in the HOF now so a certified auto might go for as much as $50. It being Mantle's last game has little consequence for a REd sox program signed by a Red Sox.





And after all, Williams as nice enough to sign it for you, the best thing you can do is see how much money you can get for it. People like you have destroyed the autograph hobby. Since players know idiots like you will just sell their autograph, it's why they charge now for everything.





Hope this helps.What is my old autographed baseball program worth?
