If i remember rightly, rust is just a metal oxide. So on a coin it would be copper reacting with the air, albeit slowly, forming copper oxide.
One method to clean a rusty penny is to create a mixture of equal parts white vinegar and table salt. Let the penny sit in the mixture for a few minutes, then gently scrub it with a soft toothbrush. Rinse the penny with water and pat it dry. Repeat if necessary.
Check where this rusty water is coming from. There are many possible causes.

When you put a rusty penny into salt and vinegar, a chemical change occurs. The acetic acid in vinegar and the salt create an acidic environment that reacts with the copper oxide (rust) on the penny, leading to a reduction of the rust and the release of copper ions. This process effectively cleans the penny, altering its composition and appearance. The change is irreversible, as the original rust cannot be restored once it has reacted.
Oxidation on a penny is caused by the reaction of the copper in the penny with oxygen in the air. This forms copper oxide, which gives the penny a dull brown color. Moisture and other environmental factors can accelerate the oxidation process.
You can use a magnifying glass to look closely at the numbers on the penny. Identify the numbers that indicate the year of minting. If the numbers are too rusted to read, gently clean the penny with a soft cloth or a mild cleaning solution to reveal the year.

In rusty pan, impurities like rust and other chemicals get contaminated easily into drinking water.This,in turn causes harmful diseases.
No, a corrosive substance is one that causes corrosion, not corrosion itself.
Sticks them together and causes them to get covered in green
Yes. The rust on the penny indicates that a reaction between the penny and its environment has occurred. Since a new material was formed from this reaction (the rust) the reaction must be a chemical reaction.
