<p>[QUOTE=&quot;RonSanderson, post: 3246220, member: 77413&quot;]Way back when I was a physics student we learned the need for operational definitions.

How did the coin get to be the way we see it now? We don’t know and cannot know. So let’s discard that from our reasoning.</p><p><br /></p><p>Instead, let’s measure.</p><p><br /></p><p>This is not a PhD thesis, so I just toss out some thoughts.</p><ul> <li>Are the colors in the right order</li> <li>Are the color transitions smooth</li> <li>Is the color cleanly bonded to the surface</li> <li>How does the toning wrap the devices</li> <li>And things you can see that are obvious visible criteria. Each of you can think of several.</li> </ul><p><br /></p><p>Combine this with [USER=17261]@BadThad[/USER] ’s observation. If one set of criteria is met, the coin is Market Acceptable and may sell for a premium (except to Kurt). If the criteria are not met, it’s not MA and should sell for less.</p><p><br /></p><p>To even ask the AT / NT question is to veer off into religion or philosophy, where pondering the unknowable is better considered.[/QUOTE]</p><p><br /></p>
