<p>[QUOTE=&quot;-jeffB, post: 3318062, member: 27832&quot;]Tungsten is less dense than gold by only about a third of a percent. Do you think you could reliably distinguish 2.8mm from 2.81mm -- a 10-micron difference in thickness, assuming identical diameter? Do you think Gold Maples are struck to that tolerance around their entire edge? I don&#039;t think modern minting technology is quite that precise.[/QUOTE]</p><p><br /></p>
