I bought this baseball from QVC in 1992. Attached are the original copy of the COA as well as pictures of the baseball. I've been trying to authenticate it by looking at other signatures Etc but I'm just not sure if it's really Mickey's signature or not. He was appearing live on the show the night that we bought the baseballs but I'm not sure that means anything. Especially since there's so many fakes scoreboard coas and baseballs floating around Can anyone tell me if it's a real Mickey Mantle signature? And, if its authentic, how much would it be worth?
