<p>[QUOTE=&quot;GDJMSP, post: 1188255, member: 112&quot;]Not at all, that&#039;s why it&#039;s weird. </p><p><br /></p><p>Think about this - a nickel is made of 25% nickel and 75% copper. It&#039;s a solid alloy. But what part of a nickel even remotely looks like copper ? You ever seen one ? I sure haven&#039;t.</p><p><br /></p><p>Now the 40% halves. The outer layer is made of a soild alloy too - 80% silver and 20% copper. So how can copper show on the edge ? It doesn&#039;t on a nickel.</p><p><br /></p><p>Now somebody is going to say but the half has a pure copper inner core. And you&#039;re right it does. But that pure copper inner core is smaller in diameter than the finished coin. And the inner core is completely wrapped, including the edge, in an 80% silver alloy.</p><p><br /></p><p>So no copper should ever show on the edge. That&#039;s why I say the only thing that makes sense to me is that the planchet for that coin was an anomally. Somehow, a planchet with an inner copper core of a larger diameter got into the mix. Which is what allowed the copper to show on the edge.[/QUOTE]</p><p><br /></p>
