<p>[QUOTE=&quot;GDJMSP, post: 2680098, member: 112&quot;]And I never said that &quot;some&quot;, stress some, metal wasn&#039;t lost.</p><p><br /></p><p><br /></p><p><br /></p><p>On the contrary, it has everything to do with it ! Let&#039;s put things into their proper perspective.</p><p><br /></p><p>For example, you listed the tolerance for a double eagle to be +/- .032 gm. Do you know how much that is ? It is one half of one grain - 1 grain = 0.06479891 gram. And the specified weight of the entire coin was 516 grains, or 33.436 grams. So what we&#039;re talking about here is that the tolerance level for the coin is one tenth of one percent. </p><p><br /></p><p>Now you claimed above that some coins came off the press out of tolerance. I won&#039;t doubt your word but I&#039;ve certainly never seen one that was, and I&#039;ve weighed more than a few of them. But let&#039;s assume some were, let&#039;s double it even. That would still mean that it was only 2 tenths of 1 percent. Even if you multiplied it by 10 to get to 1 percent it would still only be 0.320 gm ! And I won&#039;t believe for a second that any coin was off ten times its tolerance level.</p><p><br /></p><p>But the simple fact remains, the coin I used as an example in this thread was weighed when it was brand new, and when it had reached the stage of wear that you see in the pictures. So whether it was within tolerance or not, has absolutely nothing to do with anything. Because the before and after weight of the coin only changed by 0.003 grams. That&#039;s how much metal was lost by friction wear, and that&#039;s 1/10 of 1/10 of one percent !</p><p><br /></p><p>So does some metal wear away, leave the coin ? Absolutely yes ! But when you&#039;re talking about amounts THAT small, that&#039;s when you say SO WHAT ![/QUOTE]</p><p><br /></p>
