Toning Explained:

Toned coins are result of a chemical process that reacts with the surface metal of a coin. Although any coin can tone, silver and copper coins are most susceptible to the toning process. Gold coins, on the other hand, are the least susceptible. However, gold coins can still take on subtle shades of toning as they get older.

Toning occurs naturally over time. It is mostly the result of oxygen and/or sulfur reacting with the coin's metal.
