Authenticating coins that were soldered into spoons
I acquired these with some other spoons and thought these were fakes. After some research I came up with 1792 coronation 2 Ducat for Francis II and a Saint John's protection medal. I Still thought they were modern copies. I tested them and they come up specific gravity of 10, and acid test good for silver. I'm now thinking they may be genuine. Does anyone have any insight?
