Horn Silver | Coin Talk
Horn silver is silver chloride (AgCl). On ancient silver coins, it is sometimes seen as a dull gray or black tenacious deposit. I'm unaware of any easy way to remove it without harming the underlying surface, although I have seen sodium thiosulfate recommended as a removal agent (soak the coin in a solution of sodium thiosulfate).
