2 suggestions if any of the experts on this subject chime in: (1) VIDEO of coins showing this "cartwheel" effect are probably more effective than pics. (2) If pics (or video) are shown to educate or exhibit luster differences, it might be easier with gold (or silver) coins. As an example, you can EASILY see the luster on this 1908 NM WF Saint-Gaudens, as opposed to luster on nickel or certain silver coins.
I had a big ole spill typed out for you that had all kinds of things that had to do with the life of a die. Luster happens on the freshest of dies. It is different than the luster on a late die stage.
That was heavily debated in the early part of this thread which helped make it a Featured Thread, BTW, P&G. Yes, I agree with you (and the earlier posters). But I keep going back to RWB's micro-molecular analysis...the deformations in the crystalline structures...that only happens after repeated blows. I think all these are contributing factors in producing (different types of) luster.
