<p>[QUOTE=&quot;Cherd, post: 1466446, member: 24754&quot;]It seems that, with today&#039;s technology, a coin grading methodology could be developed to remove human subjectivity (and error) from the process. Laser scanners and software are available that can render quantifiable, high resolution, 3 dimensional representations of a coin&#039;s surface. A database could be developed with 3 dimensional representations of perfectly struck mint state coin designs, and then numerical grade assignments could be assigned based on each coins quantified deviation from perfection.</p><p><br /></p><p>Automated methods are also available for remotely measuring the reflectivity, refractivity, composition, and color distribution of the surfaces. All of this data could be measured, fed into a predefined algorithm, and a non-biased, completely repeatable grade assignment would be calculated. This type of method would also provide additional information that would make coin evaluation more interesting for collectors, for instance the slab could say Field: AU58, Devices: AU55, Color Consistency: 75%, Reflectivity: 80%, Net Grade AU55.</p><p><br /></p><p>The nice thing about this process is that it would provide the same results every time. You put the coin into a hypothetical machine that can measure all of these things, and the grade results pop out of the other side. I personally think that this is more reliable than some guy sitting there with a hand lens, asking his buddy next to him what he thinks, and applying grades based on his personal preferences and how he feels that day. Do you guys think that this type of grading approach would be an improvement, or would there be some important aspect of grade assignment that would be lost in the process?[/QUOTE]</p><p><br /></p>
