<p>[QUOTE=&quot;C Jay, post: 1377389, member: 13184&quot;]I recently had a dental appointment, and in the course one visit and a few X-Rays they were able to create a 3D computer model of my mouth and jaw. The things computers have become good at is performing measurements and creating models. Lets say you were to scan a series of coins at various grades and create a model for each grade, it would then be a matter of scanning an ungraded coin and comparing it to the computer models. I would think at the microscopic level, there would be a measurable difference between a coin with luster and one without. You could count the hair lines and marks within a defined area and have a degree of tolerances per grade. Another thing computers have become good at is creating paper reports. At least you&#039;ll get a detailed report on why it received that grade.[/QUOTE]</p><p><br /></p>
