Things You'll Need
Instructions
Keep the silver coin you want to tone in your pocket for about a week. Handle it several times a day to get your skin's oils on all parts of the coin.
Pour about an ounce of powdered sulfur or cigarette ashes into an envelope.
Set the coin in the envelope and seal the envelope. Place the sealed envelope in a sunny area.
Handle the envelope daily and massage the coin around in the sulfur powder.
Take the coin out of the envelope after a month.
