<p>[QUOTE=&quot;GDJMSP, post: 1375849, member: 112&quot;]No, it doesn&#039;t. You can&#039;t have luster until the metal in that area touches the die. Luster is formed by the flowing of the metal to the sides because it has met the restriction of the die. And if the metal doesn&#039;t flow, there is no luster.</p><p><br /></p><p><br /></p><p><br /></p><p>Actually it would probably be one of the easy parts partially because of what I explained above. The thing that makes wear different than a weak strike is that the metal in weakly struck spot is rather rough whereas wear is smooth. That could be quantified and identified with a minute scan.</p><p><br /></p><p><br /></p><p><br /></p><p>Agreed, it would be very tough, probably tougher than you think. But for different reasons. You see scratches not only produce incuse marks in the surface of the coin, they also produce raised marks on the surface of the coin because the displaced metal has to go someplace. So it piles up either on one side or the other or on both sides of the incuse mark. </p><p><br /></p><p>And of course on the die alone you can have lathe marks, flow line marks, die scratches, die polish lines, tool marks, doubling marks, clash marks, planchet marks, planchet flaws, die chips, die cracks, and die breaks. Each and very one of these produces marks that can be extremely similar to the others. And teaching a computer to differentiate between them all - that would be tough. </p><p><br /></p><p>Then of course you have all of the different kinds of marks that can occur on the coin after striking.</p><p><br /></p><p>These are only part of the reasons why thought is required. Something a computer cannot do.[/QUOTE]</p><p><br /></p>
