Circulation causes the surfaces to show wear. Your coin is an example of that. The paint could be removed with lacquer thinner. But be careful with this as contact on the skin can really be harmful. If it is plating, it cannot be removed that way. Sometimes people use nail polish on coins, but nail polish can remove that. But with the green on the reverse, it may have a problem in that area?
