My coin and the Morgan are subject to the same laws of physics. My coin was stored in a sulfur-rich environment for three months and acquired a layer of silver sulfide. <i>By the laws of physics</i> it should follow the same color progression as the thickness of the sulfide layer changes. And it does as I have demonstrated. The progression goes through the first of the three cycles.

My quarter has it, even though it was artificially induced. The above quarter has it, at it probably is not “naturally occuring” either. The morgans and supplementary Peace dollars have it, and they are all likely completely natural. The OP Peace dollar does not.</p><p><br /></p><p><br /></p><p><br /></p><p>All of those have a pattern while the OP coin does not.[/QUOTE]</p><p><br /></p>
