[QUOTE="GDJMSP, post: 1178318, member: 112"]As I have explained many times, die polishing was done by holding the face of the die against a large, spinning zinc plate. Now if you envision something the size of a coin die being held against a zinc plate that is several inches across it should be obvious that it would be impossible for any marks left behind by that zinc plate to curve within the face of the die or for those marks to cross one another simply because of the size relationship between the two objects. So marks such as those on this coin cannot be from die polishing. Yes these marks were on the die, but there are and were other things done to dies besides polishing them. Sometimes a coin is abraded with sharp pointed, cutting tools - think of something like a dental pick. This was done to try and remove small marks or damage to the die caused sometimes by minor clash marks and sometimes by foriegn object damage like a strikethrough. It was these tools that caused marks like this on the die. There is a difference between die polish marks and die scratches. The marks on this coin are the result of die scratches (from tool marks), not from die polishing. Every coin you've ever seen comes from dies that were polished. The very word polish means to make smooth, to remove any scratches from a surface - not create scatches on that surface.[/QUOTE]
