That green stuff that shows up on copper is called verdigris, and is also known as patina. In addition to making your penny green, it's also what makes the copper Statue of Liberty look green!The process by which verdigris is made is called oxidation. Most of the time, when copper oxidizes, it turns dark brown, like most pennies you see. When saltwater is added (like in somebody's sweaty pocket) the copper turns green instead.
Copper turns green because if forms a coating of copper acetate upon exposure to air and moisture
The Statue of Liberty is made out of a copper element. When copper erodes or is exposed to oxygen progressively, it turns green.
