<p>[QUOTE=&quot;GDJMSP, post: 626473, member: 112&quot;]Don&#039;t get mixed up here now. That is what I and&nbsp; Dannreuther was trying to explain. It is not that luster gets stronger with die wear - it merely changes from one type of luster to a different type of luster. A luster with a different look.</p><p><br /></p><p>If one truly wanted to quantify luster, meaning actually measure which luster was stonger than the rest, it would be Proofs, Proof Like coins and EDS business strikes that would have the strongest luster, in that order. This is because what you would be measuring is the actual amount of light that is reflected by a given surface. You would obtain that by firts measuring the strength of the light from the source and then measuring the strength of the light being reflected from the coin and subtracting the difference.</p><p><br /></p><p>In every case, the closer the surface of the coin was to a mirror, the stronger the reflected light would be. This is common sense, but it can be proved.</p><p><br /></p><p>So keep in mind, it is not that luster gets stronger as the die is used - it&#039;s that the look of the luster changes. That&#039;s all. Semantics maybe, but accurate.[/QUOTE]</p><p><br /></p>
