Key factors here are authenticity and condition. Presuming the signatures are genuine, the mainstay of the group are the postcards, and assuming these team-signed pieces include slugger Hank Greenberg, a safe appraisal without seeing the pieces would be in the range of $150 to 200, and likely more if in premium condition. Pictures and/or a more complete desciption would result in a simple and accurate appraisal.
