Yomiuri Giants Masao Kida Player's GOLDEN PLAYER'S MEDAL. Comes in a dedicated case. As it's from his time with the Giants, I believe it was purchased around 1965-1969. It has been stored in its dedicated case for a long time. The label on the case shows signs of deterioration. Please consider purchasing if you understand that this is a used item. Diameter: Approximately 57mm Thickness: Approximately 4mm
