<p>[QUOTE=&quot;eddiespin, post: 7386068, member: 4920&quot;]Actually, John, if I may clarify a little. I think you describe well the stages the dies go through as they age. I&#039;ve not heard it described in this detail, before, however I can say, it makes perfect sense to me. But let&#039;s get off the dies for a minute and get on the planchets, themselves. When those were struck, the metal was flowing from in to out. That is to say, it was flowing from the center to the perimeter of the planchet. That&#039;s where these flow lines that impart luster to the coins come from. They&#039;re ever so slight, but their impact is profound. Contrast that with luster imparted by the dies, themselves--which, by the way, also wore in the same way as the distribution of the metal flow on the planchets, that is to say, from in to out, or from the center to the perimeter, creating the striations, or what you will, imparting the conditions to the planchets when they were struck by those aged dies. That&#039;s luster imparted by the dies, themselves, or the die wear. My point of clarification is, luster is imparted in two ways, first, by the distribution of the metal flow on the planchet, and later, by the wear in the dies, which, again, form the same way as on the planchets, except, over time and use.</p><p><br /></p><p>We&#039;ve a lot of good threads on this, yet going back some dozen, or so, years. Just let it suffice, for anyone interested in how luster actually forms, dig those threads up, and you won&#039;t have to consult anything else, ever. We&#039;ve had some pretty big brains back then, I&#039;ll add, I have to give us the credit.[/QUOTE]</p><p><br /></p>
