<p>[QUOTE=&quot;Mike Margolis, post: 3219913, member: 88401&quot;]Yes, this method(the one I linked to) does tell you the density. This is not the same as the specific gravity test. You use the tweezers to lower the coin into the graduated cylinder and let it the coin only rest on the bottom pulling the forceps out completely to measure the water displacement only of the COIN = VOLUME. DENSITY = MASS/VOLUME. The method I have shown and given links to is density, NOT the SPECIFIC GRAVITY test. Yes their results are close. What I meant by calling it &quot;relative&quot; is that it can be undermined with a careful alloy to mimic the density of gold but this is rare. over the top with nitpicking folks. I guess it goes with the territory?[/QUOTE]</p><p><br /></p>
