It's a form of oxidation, somewhat similar to rust on iron-based metals. Copper oxide is greenish in color and is often called "patina".
Another example is the Statue of Liberty. It's copper underneath, but a century and a quarter of oxidation have turned it green.

∙ 14y agothe"green stuff " on many pennies is rust, and if you wanted to get it off then drop it in some baking soda and some vinegar
rust is normally a layer of new material building up on the outside of the material. Because we live in an environment with a large oxygen content metals are commonly oxidised(or seen to rust). The metal oxide that forms is a completely new material, so the brown suff "rust" that appears on iron is iron oxide, just as the green stuff "rust" that appears on pennys is copper oxide, years of people handling the penny, and in many different environments accelerates the rusting(oxidation process).
If you look around many old buildings used to have copper domes or statues and they are now a bright green colour, this is the same thing that happened to your penny just on a much bigger scale.

Why garlic in vinegar turns to green?
I turned white vinegar green by putting a 1969 penny in it for two weeks in the refrigerator. It turned green because of the copper in the penny reacting with the vinegar in a process called oxidization. The green was the copper oxide formed when the copper in the penny oxidized in the vinegar.

What is the name of the process that turns a penny green?
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.
