[QUOTE="ldhair, post: 2371724, member: 11540"]I have always thought that the surface of a die next to the devices becomes harder than the rest of the surfaces. I call it work hardening. Maybe the wrong term when talking coins. That would make it harder to scratch. One other thought. The grease and junk can mound up in the devices. I can see how the first wipe or two from a mint worker would ride over that mound and carry away most of the metal shavings. That could leave scratches on both sides of the device. I don't have a solid opinion on this coin but feel there may be more than one answer to everything going on with it.[/QUOTE]
