#chemicalreactions Coins undergo chemical reactions, primarily oxidation, that cause tarnishing and color changes over time. Specifically, copper in coins reacts with oxygen and moisture in the air, forming copper oxide (CuO), a black solid that covers the coin's surface. This reaction is a type of redox reaction where copper donates electrons to oxygen. | Lauro R. Cachero

Copper reacts slowly with oxygen in the air—a process called oxidation. The process produces copper oxide, a brown or black compound, or tarnish. Eventually, other chemicals from the atmosphere, like sulfur, will turn the tarnish blue or green. | Tamara Copper

copper corrosion is not as destructive because copper forms a protective outer oxide layer that discourages further corrosion. copper will oxidize due to a reaction with oxygen and liquid water or moisture in the air. Oxidation adds a blue-green color to copper, brass, and bronze. It is very easy to remove the oxidation on the copper surface but tricky.
