<p>[QUOTE=&quot;desertgem, post: 2219991, member: 15199&quot;]&quot;How can two medals have verdi gris at the sme spot without one or both being fake.&quot;</p><p><br /></p><p><br /></p><p>Verdigris is not transmitted, molded, or &#039;stamped&#039; into the metal as it is a chemical reaction that occurs after the production whether it is from a mold or die. However the mold or die could have a microscopic surface irregularity that might cause verdigris to develop easier in the same position of several examples, <b>especially</b> if they were stored together, but that is a far possibility. So both could be good, both fakes, or one of each based on verdigris.</p><p><br /></p><p>On the basis of weight and metal, I would hope the coin historians would know if patterns were made before production of different weights and metals of the same medal.I would suspect so.[/QUOTE]</p><p><br /></p>
