[QUOTE="GDJMSP, post: 1272249, member: 112"]You weren't the first and sure won't be the last ;) I make my share of mistakes, but I make a great deal of effort to make sure my comments are accurate. Yes, it is wrong. Luster on the coin is created by the flowing of the metal when the coin is struck. And it is absolutely the top layer of metal of the coin itself that is lustrous. It is not something that merely sits on top of the metal - it is the metal. And you are correct. Toning is oxidation of the coinage metal. Rust is oxidation on ferrous metals, is damage to that metal. In both cases it is the molecules of the metal itself being eaten away by the oxidation. So there is no way to call it anything but damage. But on coins, at certain stages, that damage can be quite pretty to look at ;) So while toning is damage in a technical sense, it is not thought of as being damage but instead as being an asset. And in a way it is, for the toning on the metal will also be a protective layer that will protect the coin and greatly slow down any additional oxidation as long as the coin is stored correctly. Yes, they are. And there is nothing you can do to completely stop it 100%. But with proper storage you can slow it down enough that you will never be able to notice any additional damage in your lifetime.[/QUOTE]
