Another important diagnostic for die attribution is Die Scratches (DScr). Die Scratches are a result of either a gouge on the surface of the die creating a raised line on the coin or are a result of polishing of a die during its later life. During the preparation of this book, I used the term Die Scratches to document the heavier die gouge type marks. The term Die Lines (DL) is typically used to describe the lighter raised lines on a die that could result from die polishing.
