You can darken silver coins by placing them in the presence of hydrogen sulfate, which you can obtain in great abundance from boiled eggs (it is the fart smell that comes from these delicious but wretched smelling things), or from rotten eggs if you don't mind throwing up while you're doing it.
The big problem here, however, is to find a "silver" coin, since no "pocket change" coin in North America has been made of silver in the past 30 years. You will have to find a very old dime or quarter, or you will need to purchase from the mint a current silver coin at 4 to 20 times its actual face value.
