Copper and zinc-plated pennies do not rust, because they're not made of iron. The only American pennies that could rust were the steel cents struck in 1943.
You might believe that a penny is rusting but instead it is corroding! Yes, it does not rust it just corrodes.

Well, yes, but -The only US cents that can rust are the famous 1943 wartime pennies made of steel. All other cents are made of copper, bronze, or plated zinc so they can only tarnish, not rust.Wiki User

∙ 14y agoOld pennies were made of copper, and copper does not rust. It does however oxidize, giving it an aqua green color. New pennies are mad of steel plated in copper, and steel can rust. However, this method is referred to as sacrificial protection, where one metal will 'sacrifice' itself so the other metal will not rust as fast.

Why does water not shine a penny as good as cola does?
A penny gets dirty in the first place because of being exposed to oxygen in the air, causing a chemical reaction between the copper and oxygen, which forns rust. Since water is one third oxygen, and the air only contains about 10 percent of oxygen, you can assume that water makes a penny even worse. Cola is extremely acidic, so it eats away at the dirt and rust. But if you leave it too long, it will start dissolving the penny itself.
