Message:: [QUOTE="GDJMSP, post: 698681, member: 112"]Not all die polishing leaves raised lines (incuse on the die) on the coin. Think of a Proof, fields smooth as glass that look just like a mirror. How do you think they got that way ? There are two types of die polishing, that done while the die is being made, and that done to repair the die after extensive use and wear. The first, you never see any lines on the coin. The second you do. But there's a reason for that. That reason is that what we call die polish lines is really a misnomer. What we call die polish lines are not caused by the repair polishing. Rather they are what is left over after the repair polishing is completed. The repair polishing is done to try and remove the lines on the die which were cause by repeated metal flow during extended use or clashed dies. Instead of calling them die polish lines, we should call them die wear lines. That would be a more accurate name. But it is what it is and we accept it.[/QUOTE]
