Random title: Carbon spot
Explanation: A spot seen mainly on copper and gold coins, though also occasionally found on U.S. nickel coins (which are 75% copper) and silver coins (which are 10% copper). Carbon spots are brown to black spots of oxidation that range from minor to severe – some so large and far advanced that the coin is not graded because of environmental damage
