<p>[QUOTE=&quot;GDJMSP, post: 1377562, member: 112&quot;]Agree with everything you say Mike. Dear God did I just say that ?&nbsp; <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie9" alt=":eek:" unselectable="on" unselectable="on" /> <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie8" alt=":D" unselectable="on" unselectable="on" /></p><p><br /></p><p>I would further comment that there is far more to it than just considering what most people think are the subjective aspects of grading. For a computer to be able to grade a coin it would require and entirely different grading system than the one we use now. Few people ever seem to consider that though. </p><p><br /></p><p>For example, lets take a single grade like MS65 as described in the PCGS grading book. Their description is as follows.</p><p><br /></p><p>MS65</p><p><br /></p><p>Marks - There may be some scattered marks, hairlines, or other minor defects. If the flaws are in a main focal area, they must be minor and few. Hidden marks and hairlines can be larger. On dime-type and smaller, they almost always must be in the devices or must be very minor if they are in the fields. On large coins, there can be marks/hairlines in the fields and in the devices, but no major ones.</p><p><br /></p><p>Strike - The coin will be well struck.</p><p><br /></p><p>Luster - The luster will be at least average (almost always above average), and any toning can only slightly impair the luster. Copper coins can have mellowing of color for Red and unevenness of color for Red-Brown or Brown coins. NOTE - there can little minor spotting for copper coins.</p><p><br /></p><p>Now I could go on the say what it says about Eye Appeal but there is little point in doing so. The point I am trying to get across is that even with what we have listed here, a computer simply could not do that. The reason the computer could not do that is because nothing is quantified or qualified. </p><p><br /></p><p>Every use of the words such as - minor, major, few, some, average, slightly, main, unevenness - all of these words would have to precisely described, defined, sized and assigned specific numbers. </p><p><br /></p><p>None of that has ever been done. Nobody knows how exactly how big &quot;major&quot; is or how small &quot;minor&quot; is. How many is a &quot;few&quot; ? How many are &quot;some&quot; ? All of this is subjective, every bit of it - 100%. There is nothing in grading that is quantified and qualified.</p><p><br /></p><p>And a computer simply cannot deal with that. That is why thinking is required in grading.[/QUOTE]</p><p><br /></p>
