And it is those same qualities of the ridges that also helps to define how the various types of luster tone. In other words, it's the different types of luster that explain to a large degree why different types of coins tone differently than one another.

Die wear, and the lines seen on coins caused by wear due to metal flow, does not increase luster, it decreases luster.
