I have a couple "2 Francs" coins (1932-1940). When I try to enter them in to "My coins" it indicates that "the coin(s) do not exist in the catalogue yet? Add it yourself!" I'm not sure if it indeed is not in the catalog and if not, exactly where and how does someone acquire the necessary data to "Add it yourself!".
I've searched the web and found "NumisCorner.com" that has one for sale with adequate data.
