<p>[QUOTE=&quot;GDJMSP, post: 8667147, member: 112&quot;]You&#039;re looking at high magnification pictures of a Morgan and Peace dollar. A visual explanation for the reason why Morgans and Peace dollars tone differently - it&#039;s because their surfaces and thus their luster, is completely different from each other. And they are completely different because of the different finishes applied to the dies of each series. </p><p><br /></p><p>Every coin series there is has a different (unique) type of luster than every other coin series. For example, Seated, Barber, Walkers, Franklin, and Kennedy half dollars, each one has a different type of luster. And this is proven in two different ways. One is that all one has to do is look at them side by side and you can see that the luster is different than that of the others. The 2nd is by taking highly magnified pictures of the different series like those shown above and you can also see the differences in the types of luster. </p><p><br /></p><p>And that&#039;s exactly how those high mag pictures posted above came to be. Years ago, we were discussing this same basic subject, and when I explained basically the same thing I just said above in this post, another member, if memory serves it was&nbsp; [USER=6641]@USS656[/USER]&nbsp; , took high mag pictures of different coin series of the same denominations to see if I was correct. And he discovered that yes, indeed I was correct. Every coin series there is has its own unique type of luster. And the bottom line is that it is each unique type of luster that causes our eyes to see what we see when look at a coin, toned or untoned.</p><p><br /></p><p>This is all further explained in much more detail in my posts found in these two threads - </p><p><br /></p><p><a href="https://www.cointalk.com/threads/what-you-need-to-know-about-the-science-of-toning.84670/" class="internalLink ProxyLink" data-proxy-href="https://www.cointalk.com/threads/what-you-need-to-know-about-the-science-of-toning.84670/">https://www.cointalk.com/threads/what-you-need-to-know-about-the-science-of-toning.84670/</a></p><p><br /></p><p><a href="https://www.cointalk.com/threads/luster-a-guide-for-beginners.58435/" class="internalLink ProxyLink" data-proxy-href="https://www.cointalk.com/threads/luster-a-guide-for-beginners.58435/">https://www.cointalk.com/threads/luster-a-guide-for-beginners.58435/</a>[/QUOTE]</p><p><br /></p>
