This is a hand-signed baseball by the well-known Bobby Valentine. It's a rare signed ball, written on a 2000 World Series official ball. When purchased, it only came with the ball, no certificate of authenticity. A Steiner hologram is attached, and the signature appears to match photos found online. I purchased it only for the photo on another site. I am selling it to organize my collection. A protective film is applied, and I will include a new UV-cut ball case. #Dodgers #ShoheiOhtani #YoshinobuYamamoto #RokiSasaki #Ichiro #YuDarvish Thank you.
