A characteristic which occurs mostly on proof coins as a result of a piece of lint on the die or planchet during the striking process. This lint creates an incused, scratch-like mark on the coin. Lint marks are wider, deeper, and more visible than hairlines. They are also identifiable by their interesting thread-like shapes. Since a lint mark is mint-caused, it has a much smaller effect on the value of a coin than a hairline of equal size or prominence.

The designing of a die so as to create a shallow, relatively flat field upon the surface of a coin in order to improve die life.

The brightness or brilliance of the coin’s metal. The luster of a coin can vary considerably due to factors such as wear, polishing of dies or planchets; or exposure to chemicals, humidity or temperature extremes.
