So I dug this 1916 Merc the other night and the black wouldn't come off at all. Not even the tried and true method of baking soda. Someone on my facebook group page told me about a different method that worked wonders and its not electrolysis. I took the coin and put it into a small piece of tin foil. I spit in the tin foil and sealed up the coin. It quickly became hot and smelled like rotten eggs, just as he told me it would. After 15 seconds or so I took out the coin and below are the results after a little shining with baking soda. Learn something new every day...
