With some things, like 19th century medals, it can be virtually impossible to find the medal with it's original case. There was a certain 1904 Louisiana Purchase medal I wanted for several years, but wanted it with at least the original box. It turned up finally, and even with the original paperwork describing the medal, the designer, how it was minted etc. Crazily, it turned up in Northern England of all places. On the other side of the water from where it was issued etc, and with all the original box and paperwork. It does happen, you just have to be intrepid.
