1985 AllStar Game Baseball

[jets526]

I recently found a baseball that is signed by 27 members of the A.L. and N.L. teams at the 1985 All-Star Game. Currently I have 20 of the names

Gary Carter
Eddie Murray
Don Mattingly
Ozzie Smith
Jim Rice
Ricky Henderson
Nolan Ryan
George Brett
Mookie Wilson
Lou Whitaker
Dwight Gooden
Carlton Fisk
Dale Murphy
Bert Blyleven
Jack Morris
Tom Herr
Steve Garvey
Dave Winfield
Lance Parrish
Dick Williams

I have a little more deciphering to do with the sigs but If anyone who reads this has any ideas about finding out the value or would like to guess the value themselves please help.
Thanks

Dumb question probably, but just to be sure, they are real autographs, right? Not just a stamped ball?

I haven't gotten it authorized yet but my grandfather had an "in" with the Yankees back then. He was at the 1985 All Star game and in the clubhouse.

I also have another ball which I think is stamped. Is there a way to tell for sure.
