<p>[QUOTE=&quot;KurtS, post: 2253112, member: 11786&quot;]That table on silver fineness, and how it relates to SG, is well-known in the metallurgical/jewelry industry. These are consistent, scientifically-calculated figures for Ag/Cu alloys and they also match the measured data for reference samples. You can <a href="http://www.hauserandmiller.com/reference/melting.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.hauserandmiller.com/reference/melting.html" rel="nofollow">do the math yourself</a>, or find the source.</p><p><br /></p><p><br /></p><p><br /></p><p>But in regards to sample nr. 13, we&#039;re talking about a mint spec of .925, <i>not .999...</i>so I find your point rather confusing<i>.</i></p><p><br /></p><p><br /></p><p><br /></p><p>I would <i>respectfully suggest</i> there&#039;s a <b>big difference</b> between doubting my findings, and using your suspicion to declare that our methodology is inherently faulty--due to a belief that all mints, for every year, are &quot;within spec&quot;--an unknown variable after all. Respectfully, such unsupported conclusions aren&#039;t science; the <i>burden of proof is upon you</i> to provide some data backing that conclusion. And in this case we&#039;re discussing <i>data for 5 different countries</i>; we should admit <i>there is potential</i> for these discrepancies.</p><p><br /></p><p>As I said before--SG tests are not <b>elemental compositional tests</b>. Let me be <b>very clear</b>: I am <b>not </b>making some final judgment on the motives/integrity of these respective mints. For my own benefit, I have conducted enough of these SG tests to be intrigued by the results--<b>that&#039;s all, make your own conclusions. </b>Regarding assays, this is done now by XRF. As I said before--I will be posting more results as my research uncovers new data. Take note of that last chart--which are XRF&nbsp; elemental assays of various silver coins. So for the future, I&#039;ll be focusing on such analyses <b>exclusively</b>.[/QUOTE]</p><p><br /></p>
