[QUOTE="GDJMSP, post: 1429362, member: 112"]I would agree that some, stress some, of the lines are die polish lines. But some of them are not die polish lines. What you always have to remember is that there are several things that can create lines on a die. Die polish lines are only 1 of them. There are also die scratches, which is the most common after die polishing. And then there are die gouges, tool marks, and lathe lines to name a few. And you have to remember that die polish lines always, always, always, share one common characteristic - they can never criss-cross, they are always parallel. So when you see criss-crossing, raised lines on a coin, only some of them are die polish lines. There are also different things that can cause raised lines on a coin besides the things I mentioned above. A lot of folks don't realize for example that a scratch on the coin itself creates not only an incuse line, that scratch also creates a raised line on the coin. This is because the metal displaced by the scratch has to go somewhere, and that somewhere is a raised line right beside the incuse line.
