Lint mark

Definition:

A characteristic that 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 distinguishable from hairlines by their evenness of depth and lack of raised ridges on their borders. 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 grade and value of a coin than a hairline of equal size and prominence.
