Alaska Territorial Guard 1942-1947 Medal and Ribbons in display case.

I don't have a picture of the exact item because I am at work and my camera is at home. The above pictures are similar/exact except my item has a 3rd metal ribbon and is in a display case. One of my customers gave this to me. It was his dad's. Does anyone know how much this would be worth. I told him to keep it as a memento of his dad but he said it has just been sitting in a drawer for years. Any idea what it is worth? You can email me at johnhubby at yahoo dot com. or respond here. thank you very much.
