    How so? Unless the further polishing was done with enough rigor and remove evidence of prior polishing, it is absolutely possible to polish the dies, rotate it a bit, and re-polish that would show as criss-crossed die polish.

    That's the point Mike, it would be dang hard for it not to remove it because of the way die polishing is done.

    I think we're going to have to agree to disagree on this one too. :(

    What do you think is the reason it get's held to a 64 or lower?
    Take a look at the last picture he posted with the grade and realize that the first pictures he is showing it very large and in a cent it's even more enlarged. Grading companies don't look at them with microscopes they use 3x to 6x only because any more then that and your just nit picking items that are not really seen. The picture he shows with the whole slab and the grade, well it looks like a very nice Lincoln right?

    And Doug, I have to disagree with you on this one also. Those are die polish lines and the point in different aways because the person polishing them just turned the coin and might have been polishing with something smaller then normal. IMO

    But they are all polished with the same thing - every time. It's a large zinc plate spinning very fast just like the wheel on a bench grinder.

    So could the use say the corner once then the edge and hit it a few times because they are new to using the machine and not the standard way?

    No, they couldn't. There is no corner, it is a round, flat zinc plate. And if they even touched the die to the edge of that plate for even a half second - the die would be ruined because it would have a groove cut into it.

    And they have to be very careful and make sure that the die comes into contact with the plate completely flat. Or else the outer edge of the die would be ground away and then it wouldn't work right anymore.

    Could this flat zinc plate get grooves like a rotor on brakes that needs to be turned?

    Extremely unlikely. For one zinc is much, much softer than die steel. That's why it is used to polish it.

    I fully understand what your saying here. The die polish lines lose 3 points just for eye appeal and all the small dings in the secondary focal area's brings this coin to a 64 easy. Wasn't gonna say anything since I had dropped out weeks ago for the same reason. The TPG's have thousands of coins pushed there way constantly and they DO MISS ALOT...
