<p>[QUOTE=&quot;ToughCOINS, post: 2993084, member: 20480&quot;]I do not place much stock in the claims of those who believe that hardness testing is conducted on planchets.&nbsp; </p><p><br /></p><p>The companies that manufacture the coil stock from which the planchets are blanked provide test results (better known as &quot;certs&quot;) which identify, among other traits, the hardness of the coil stock at the request of the mint in order to eliminate the need for the mint to test the coil.</p><p><br /></p><p>This is done because testing the coil for hardness is something the mint is ill-prepared to do, and because the mint does not want to set up the coil for blanking operations, only to have to take it back down if the coil is too hard.</p><p><br /></p><p>There is only one foreseeable circumstance in which I can envision the mint performing a hardness test on a planchet.&nbsp; It might be done only if the mint was having quality problems, and suspected that the coil hardness was not that certified by the supplier, in which case the planchet would likely be grabbed from the feed hopper, taken to the lab for testing, and be kept for documentation of findings afterward.[/QUOTE]</p><p><br /></p>
