What is Toning?
A numismatic term that describes favorable discoloration on the surface of a coin due to oxidation and other chemicals in the air acting on the metal. The appearance of toning depends on the composition of the coin. Whether discoloration is considered toning, as apposed to tarnishing, is entirely objective to the collector.
