<p>[QUOTE=&quot;GDJMSP, post: 2253093, member: 112&quot;]Yes, it is that much of a difference in specific gravity - not fineness of the metal.</p><p><br /></p><p>Using the table you provided, and I have no idea how accurate that table is, or is not,</p><p><br /></p><p><br /></p><p><br /></p><p>- the specific gravity of .999 silver is 10.49, while .500 silver is 9.68 which equals a 7.8% difference. But a 50% difference in the fineness of the metal. So your 6.6% difference in specific gravity is HUGE when it comes to the fineness of the metal.</p><p><br /></p><p>And I&#039;m just having a hard time believing that govt. mints would debase their coins that much. I&#039;m not saying they didn&#039;t as I&#039;ve never tested any of them to find out. But I do know that each and every one of them run their own tests, actual assays, on all of their precious metal coins. And all of those tests show that the coins are within spec in regard to fineness of the metal.</p><p><br /></p><p>That is what makes me so skeptical of your specific gravity tests.</p><p><br /></p><p>So for your own benefit, I would suggest taking one or two of these coins you are testing and have an actual assay done on them because - something just isn&#039;t right here ![/QUOTE]</p><p><br /></p>
