<p>[QUOTE=&quot;RonSanderson, post: 2543938, member: 77413&quot;]I thought at least someone would suggest that this was a poorly mixed alloy that created a puddle of pure nickel. Let&#039;s say that puddle had a couple of outlying swirls. When rolled out flat there was a region of harder metal at the center and another at the lower edge. Since nickel is hard to strike (perhaps it was partially crystallized?) it did not flow properly and left deep striations instead of smooth luster. You could explain a consistent set of directional lines as coming from the direction of the impurities of the original planchet.</p><p><br /></p><p>Just a thought, mostly because I&#039;m having a hard time reconciling a chemical event that was harsh enough to cause damage like this, but that also left no other trace in the luster or toning.[/QUOTE]</p><p><br /></p>
