<p>[QUOTE=&quot;KurtS, post: 2253635, member: 11786&quot;]<b>Thanks </b>Gxseries--for checking those figures against the math. In retrospect, I should have elaborated--some of those figures provided came from tables used by the jewelry industry. Those I calculated myself <i>match yours</i>; the discrepancy in others may be due to using <i>actual lab results</i> rather than pure calculation. </p><p><br /></p><p>I do agree there are assumptions present. Even if our methodology is reasonably sound, SG tests simply can&#039;t tell you the composition. We might infer the debasing is due to copper, but we&#039;ll never be sure without an elemental analysis. Whether or not we dislike the idea of debasement in modern coins, I think we should admit there&#039;s a <i>huge potential for monetary gain</i> for doing so. And I think all of us know how much money drives things in our world. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie2" alt=";)" unselectable="on" unselectable="on" /></p><p><br /></p><p>All said--I&#039;m <b>not comfortable</b> with discussing abasement in any detail based on simple SG tests. There are too many unknowns, coupled with the fact that I&#039;m not a professional lab so my results aren&#039;t rigorously scientific--even if they suggest something is going on with silver coins. For that reason, I&#039;m giving up with discussing SG in favor of elemental analysis via XRF. Thanks all for the stimulating discussion. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
