<p>[QUOTE=&quot;desertgem, post: 7814636, member: 15199&quot;]Yes, usually not , but the coin surface itself is most important.</p><p><br /></p><p>[ATTACH=full]1343212[/ATTACH]</p><p><br /></p><p>this is the surface of a Unc. Morgan&nbsp; x400 with a lab microscope, not USB type.&nbsp; If we could see this cross-surface it would be like inverted&nbsp; VVVVVVV&nbsp; &nbsp; V&#039;s.&nbsp; Chemical deposits on the sides interact with the light being refracted back. The wavelengths of the refracted light rays determine the color that the eye sees. Over time, the reacting layers can thicken and the color gets deeper until final &quot;black&quot;.&nbsp;&nbsp; With a nice toned MS Morgan the colors when the coin is rotated can vary . If the coin is worn down, the refraction interaction is less and less, until no real toning other than dark occurs.</p><p>&nbsp;&nbsp; &nbsp; </p><p>For comparison here is a photo comparing the Morgan MS with a Peace MS at 100X,&nbsp;&nbsp; Morgan on Left , Peace on right .</p><p>[ATTACH=full]1343213[/ATTACH]</p><p><br /></p><p>Notice the Peace doesn&#039;t have the ridges that we see on a Morgan, so any natural toning will not be as colorful or sharp as on the Morgan.</p><p><br /></p><p>Hope it helps,&nbsp; Jim[/QUOTE]</p><p><br /></p>
