Does anyone know how much this is worth?

I recently found a golf club that was ped down through my family and it is a ping anser 3 with either a br or copper alloy head on it. it has the original grip and orginal shaft. As far as i know it has not been played with much and looks to be in great condition, a def. 8.5 out of 10 if not better. was manufactured in arizona i believe about forty to fifty years ago. thanks for looking.
