<p>[QUOTE=&quot;ToughCOINS, post: 2779071, member: 20480&quot;]All true enough Doug.&nbsp; I could have been more technical with the explanation, especially regarding what comes first - the chicken or the egg (flow of the planchet metal or erosion of the die) - but I chose to simplify, as most people will not relate to flow lines they cannot and will not see on the first coins struck from new dies.&nbsp; They definitely exist, but are not readily apparent, even under significant magnification.</p><p><br /></p><p>Regarding the &quot;lessening of the luster&quot;, I&#039;m not sure whether I agree or not.&nbsp; The reflective intensity per unit area certainly drops with subsequent strikes, however, the total reflective area increases as the surface of each subsequent coin becomes more deeply furrowed.&nbsp; Measuring the total reflectance of the surface of two coins struck many thousands of strikes apart with the same die, and measured under exactly the same lighting would likely tell the story.[/QUOTE]</p><p><br /></p>
