[QUOTE="RonSanderson, post: 2569655, member: 77413"]Maybe I used the wrong terminology. As I understand it... Polish marks on the die would be caused by an abrasive material removing minute amounts of metal from the surface of the die, causing small grooves. These grooves may span small devices as the abrasive polishing would bridge across the gaps (such as the incised numerals in a date). The would also seem to end at features such as Lincoln's nose and the edges of wheat ears. Upon striking the inverse image would be created - small raised lines on the surface of the coin, that do not affect the devices because the polishing did not reach into those cavities. I [I]still[/I] haven't seen the lines shown in the picture. The magnification and lighting have to be particular to reveal them. I will try some pictures, or at least report on the accuracy of the color, since I am away from the coin at the moment.[/QUOTE]
