<p>[QUOTE=&quot;Conder101, post: 32871, member: 66&quot;]The problem is Roy, what have you really measured?&nbsp; If the high points on the design are opposite each other you can get one figure, if they aren&#039;t you get a different one.&nbsp; A weakly struck piece will give you a different figure than a strongly struck one.&nbsp; For example look at 2004 nickels.&nbsp; The planchets used at Denver and Philadelphia are same diameter and thickness.&nbsp; But after striking a roll of Denvers is &quot;two nickels&quot; longer than a roll of Philadelphias because the Denvers are struck at a higher tonnage and have the rims struck up higher.&nbsp; So trying to measure the thickness of the final coin can&#039;t give you good information about the thickness of the original planchet unless you made point thickness measurements at a few dozen points and averaged them.[/QUOTE]</p><p><br /></p>
