[QUOTE="GDJMSP, post: 1019022, member: 112"]Because you are not polishing the die by hand for one thing, nor are you using a piece of sandpaper. Dies were polished on a flat, spinning zinc plate.

Granted, I understand what you saying. But you have to realize that when this is done by a machine the number of revolutions from just a few seconds of contact between the die and the zinc plate completely obliterate any previous die polish lines. It's not like when do something by hand. When you see crisscrossing lines on a coin, and yes they do exist, what are seeing are die polish lines that crisscross with flow lines in the die that were not completely polished out, or subsequent, newer flow lines that formed after the polishing. And since flow lines always form in a radial direction, none of the lines on this coin can be die flow lines. So they have to be from something else, I just don't know what. As I mentioned earlier, that lump of raised metal on the obverse, it is impossible for that to have been caused by die polishing. The only thing it could have been caused by, that I can think of, was some sort of tool mark. But that doesn't make sense either. Like I said - it's a puzzling coin.[/QUOTE]
