As the family takes it back again and it goes through the process, maybe one or two generations, the significance of that medal will be gone again and it might end up back on the market. So there's never any guarantee, if that medal goes back into a family setting, how that medal will be treated.
There is possibly a guarantee that if a medal goes into a museum setting, it will end up in a pull-out drawer somewhere and may be pulled out once every ten years.
