<p>[QUOTE="GDJMSP, post: 2899817, member: 112"]One last thing, I also think it important to at least mention this. Any time, on older coins or even modern coins, that you see die polish lines on a coin it's because somebody at the mint screwed up - made a mistake. You are never supposed to see die polish lines on a coin, not if they do their jobs right. When you do see them, it's because the final stages of polishing were not even done. If they had been - you wouldn't, couldn't see any die polish lines. And, about the only time you do see them is when a die has been re-polished after it has been used for a while. It can be re-polished to remove, or attempt to remove, clash marks or just because the die has too many or too severe wear lines from metal flow on it. Those are about the only times dies are re-polished. </p><p><br /></p><p>But even the re-polishing follows the same process, they start out with a course grit and work their way up to a fine grit. The course grit is necessary to remove clash marks or wear lines. The course grit will leave visible die polish lines, the finest grit will remove all trace of them. So when you see die polish lines on a coin, it's because somebody skipped the final polishing sequences. They screwed up, got in a hurry or just plain skipped it because the dies were needed to continue production.</p><p><br /></p><p>Also, if you follow the processes I have described in these posts, and think about it for a few minutes, it soon becomes quite evident that what I have been trying to tell people for many, many, years now about how die polish lines can only be in straight lines and never criss-cross each other. It simply cannot happen - because of the process.</p><p><br /></p><p>Hopefully some will find all of this useful.[/QUOTE]</p><p><br /></p>
