Heat place it in an oven.
Sulfur is the active toning agent most of the time.

Sometimes just wrapping it in paper and leaving it on a desk for a few months does it.

Keep the coin over flame. Several layers of silver oxide form on the silver coin. These layers can disperse the sun light into VIBGYOR.
