<p>[QUOTE=&quot;desertgem, post: 2117210, member: 15199&quot;]The uncirculated Morgan dollars have a different surface type than the newer Peace dollares. Below is Morgan on the left, Peace on the right. 100X with a compound scope. Notice the higher peaks/valley ratio of the &#039;flow&#039; lines on the Morgan compared to the Peace. Like very coarse sandpaper and the Peace with very low peak/valley ratio, very fine surface. When thin film sulfide from toning happen on the Morgan, there is greater diffraction ( similar to Fresnel lens), this doesn&#039;t happen on the Peace. Also why the &#039;wagonwheel&#039; appearance on the Morgan appears greater. The Peace can be toned, but the toning will look much &#039;flatter&#039; and on the coin surface than the Morgan. </p><p><br /></p><p><img src="http://i455.photobucket.com/albums/qq279/desertgem/comp100.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /> </p><p><br /></p><p>Below is the same at 400X ( and these are true magnifications rather than the ones you see on ebay). It is approximately in the same area. </p><p><br /></p><p><img src="http://i455.photobucket.com/albums/qq279/desertgem/comp400x.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /> </p><p><br /></p><p>So there are good reasons why natural toning and artificial toning occurs more on Morgans. Peace toning is more general in color and underlying luster.[/QUOTE]</p><p><br /></p>
