Copper reacts with oxygen, carbon dioxide and sulfur dioxide to form compounds called a "patina", which can very loosely be thought of as a sort of rust. These compounds have a greenish cast to them.
The best example of patina is the Statue of Liberty. It's made of copper and when new it looked like a shiny penny. Exposure to the atmosphere for over a century has caused the familiar green color.
