I have acquired a collection of various items. Among the collection are several signed baseballs. There are 2 signatures that I can't identify.
The first one has Hank Aaron on the sweet spot. There is another signature below. Not sure who it is.
The second one has Tony Gwynn (edited to change this signature to Juan Guzman) , Reggie Jackson, and Sparky Anderson. The fourth signature is the one I can't identify. One guy told me that he thought it was Carl Yastrzemski, but I don't think it is. It doesn't look like any other Yaz signature I've seen, but it is close enough that I guess it is possible.
Another question regarding the second ball. Is it possible that this is a game used ball (or at least batting practice used)? Is that a bat mark below the Reggie Jackson signature?
Here are the pictures.
Here are the other signatures on the second ball along with the black mark. Is it a "bat" mark?
