I'd say over about $4000 for a baseball signed by him in 2009.
Anyone, or all of the ballplayers that played in the 1985 All-Star game could have signed any given baseball. There was also more than one baseball signed, and it would be impossible to know who signed The baseball. You have to be more clear on what you are asking.

Signed autographThere is no difference between signed memorabilia and autographed memorabilia. It is just deference in terminology. A signed baseball is the same as an autographed baseball and the same value. An autograph is signed. You could sign a check or a document but the signature would not be considered an autograph. You sign a baseball or a photo and the signature is an autograph.
