<p>[QUOTE=&quot;mikenoodle, post: 823907, member: 307&quot;]this is how they do it chip:</p><p><br /></p><p>The coin is examined and graded by multiple graders (I am not certain how many). They each evaluate the coin. When all have evaluated the coin, the coin is then given a final grade and sent to be encapsulated and the grade verified by yet another grader. If the verifier disagrees, the coin will be tagged and sent to other graders for discussion and possibly to be compared to a grading set. (grading set - a set of actual coins in grades from top to bottom for comparison purposes)</p><p><br /></p><p>That said, it is done by several people, but independently by each one and if they all agree they ship it out slabbed, if they don&#039;t they sit down and look harder and discuss why they disagree. (Kind of like here.) As much as I don&#039;t like the TPGs, if I was going to design a system that would be as close to incorruptible as I could make it, this system would fit right in.[/QUOTE]</p><p><br /></p>
