I have a beautiful John Salley dagger which I purchased from him almost 40 years ago. It is a short sword with a scrimshawed handle in a wooden sheath. It was pictured in BLADE magazine and the editor of the time put me in touch with John. I am getting on in years now. I wanted to place this as I did spend about $800 on it back then. But eBay canceled my ad when I mentioned it was an ivory handle. I have a very dim memory of a John using the word fossil but I have zero paperwork on this. Does anyone have any knowledge as to what materials John used to use? Does anyone know any place that for a fee could determine what kind of ivory this actually might be? My goal is not to make money although I bet this is worth a couple thousand by now. Oh, the scrimshaw of a goblin in armor was done by Bob Engnath. The sword is signed by both in the metal and scrimshaw. I might consider placing this with a museum if that was the best way to ensure it survives! Any advice?
