<p>[QUOTE=&quot;Ed Zak, post: 13233, member: 824&quot;]<b>It is going to work someday...sooner than we think!</b></p><p><br /></p><p>The use of lasers are used today in a variety of industries that deal with <u>custom</u> services and appliances.&nbsp; This technology is in fact <b>REAL</b>.&nbsp; For instance, the dental industry is now using lasers to scan teeth whereby milling machines can exactly duplicate the tooth in a new restored material...in about 15 minutes while you wait.&nbsp; Height, depth, size, etc., are all scanned, assigned data, calculated and now made instantly.</p><p><br /></p><p>Of course, no two people have the same exact teeth and the same can be said about coins.</p><p><br /></p><p>Matter of fact, laser digital companies have perfected the use of strands of laser lines (versus the single dot we see in pointing devices) to scan surfaces &quot;repeatedly&quot; whereby changes in surfaces can be detected within 10 to 20 microns.&nbsp; Way smaller than the human eye!</p><p><br /></p><p>Imagine lasers scanning the surface of a Walking Liberty and givining each &quot;pixel&quot; area a value (x,y,z).&nbsp; Compare the scanned data to that of the &quot;standard&quot; and the computer using calculations for each area will aside a technical grade based on the collected data from 1 to 70!</p><p><br /></p><p>I have seen this technology work and spoke to the engineers about our little hobby and how much of an uproar takes place between a MS64 grade and MS65 grade...by grading experts with their <i>subjective</i> opinions.&nbsp; They told me that it can happen.&nbsp; The key is what will be considered the &quot;perfect&quot; coin that all others (the variable) will be compared against.&nbsp; That will be a debate all by itself,</p><p><br /></p><p>I bet you this...it is going to happen. At least at the very minimum, grades will eventually be assigned from a technical standpoint for strike, relief, etc. using this type of technolgy.</p><p><br /></p><p>PCGS may have tried this...but the key is how to accurately scan coin&#039;s surfaces for all of the important items that determine grade.&nbsp; I am sure PCGS knows coins, but laser scanning is something only a few understand.[/QUOTE]</p><p><br /></p>
