<p>[QUOTE=&quot;Kasia, post: 2354996, member: 31533&quot;][ATTACH]479812[/ATTACH] </p><p>So basically one is saying that luster is created by &#039;shallow&#039; grooves (may be off on what the term actually is on a fresh die) and as the die is used and the planchets are struck, the face of the die wears down, which still gives luster up until the point that the grooves are not shallow enough to reflect light properly for luster. It still will from then on create the other type, so to speak, of luster, which isn&#039;t properly luster because it is being created from too deep of grooves to reflect the proper light. People just call it luster because they are recognizing it as shiny and reflective, but more properly it is not luster because that has been destroyed in the minting by flow lines on the die being too deep or wrongly angled, or such. And of course, since luster is such a ephemeral type of quality, easily destroyed just be rubbing down the small amount of proper depth grooves that create it, it is necessary to be able to properly spot it. </p><p><br /></p><p>Is this correct?????[/QUOTE]</p><p><br /></p>
