When I was younger, I stay with some friends during the day while mom and dad worked, and they had a coin-op GE FF in Harvest Gold. The front of the coin box was removed, and they would use the same quarter over and over. This was in the early to mid 70's. There were 6 people in the family, so it was used almost daily. I think it lasted until the late 80's or early 90's I remember walking by their house and seeing in the trash.
