<p>[QUOTE=&quot;quarter-back, post: 1826511, member: 47022&quot;]OK.&nbsp; I re-did the tissue test under normal daylight conditions and with thinner tissue. Below is the result.&nbsp; The subject coin is in between a silver war nickel on the left and a typical alloy nickel on the right.&nbsp; To my eye, the subject nickel is more like the typical alloy nickel than it is to the silver one. </p><p><br /></p><p>[ATTACH]300690[/ATTACH]</p><p><br /></p><p>Also, I have an electronic balance that measures to 0.01 grams.&nbsp; I would like to do the specific gravity test, but there are as many versions of how to do it as there are people posting about it.&nbsp; I can weigh the coin dry and then submersed in water, or I can weigh the coin and then weigh the water with and without the coin submersed - both have been presented as methods.&nbsp; Further, there are numerous different calculations listed. Does anyone have a definitive method and the appropriate calculations. <strike>Finally, I can&#039;t seem to find a definitive set of specific gravity measures for the two nickels.&nbsp; If they in Bowers&#039; or Nagengast&#039;s books, I can&#039;t find them.&nbsp; </strike></p><p><br /></p><p>TIA for any info you may be able to provide[/QUOTE]</p><p><br /></p>
