Echizento;
Those medieval coins you discuss are fragile and thin silver, plus if it crystallized as others have said you could have a very unfortunate ending. I have just been reading about this creation of the alloy of silver, maybe 5% in the whole coin, then the acid wash out the copper on the surface to make the silver "plate" look. I wonder if this whole process makes these coins work better for unbending? Now I wonder if someone took a coin like this today, and lightly acid washed away the copper, might a silver plate look reappear? Apparently they did this pickle solution before they struck it so not sure if this would be successful.
