I am curious as to what the community feels about adding signatures to older baseballs. For example, I have a 1961 Yankees Team ball, and I recently had Bob Turley re-sign it because his original signature from 50 years ago was almost totally faded.
I have another situation where I have a 1971 NL All Star ball with some great sigs, but missing Aaron, Mays, McCovey, Bench. If I add these sigs with their current style, how does it affect the value of the ball?
