The black stuff on pennies is often caused by a combination of oxidation and tarnishing, particularly from the copper surface reacting with moisture and air. It can also result from the presence of dirt, grease, or other contaminants. In some cases, the black residue may be the result of corrosion if the penny has been exposed to harsh environments. Cleaning with a mild acid or vinegar can sometimes remove this black substance, but it is generally not recommended, as it can further damage the coin.
