old ice box

My aunt said this has been in her family since she was 10 years old. She is now 70 years old. She was wondering what it would be worth. It is white with green trim around the doors. There is 1 large door and 2 small doors. There is very little damage to it. There is the number 711 stamped on the large door plus the one small door. It has a tag with it that said it came from Pittsburgh, PA
