Corrosion
- Explanation: Chemical reaction on the surface of a coin. Corrosion can result from a coin coming in contact with other things (chemicals) including chemicals in the air. This can come about because of things coming in contact with the coin years earlier. Corrosion damages a coins surface and is usually worse in copper, nickel, zinc, and silver coins. Some experts think that toning on the surface of a coin may help slow down this harmful process
