<p>[QUOTE=&quot;mgmgmg75, post: 2715035, member: 75114&quot;]When we speak of woodies, it is caused by incomplete mixing of the alloys.&nbsp; Any impurities in the metal would be seen in the finish product and called lamination&#039;s.&nbsp; Just a small amount of impurity, 1/8 inch in diameter, would roll out to a long &quot;stringer&quot; several inches long by the time it goes through the last mill.&nbsp; This stringer is never seen, and is common, unless it comes through to the surface, which could peal off in subsequent operations.&nbsp; We have seen coins like this.&nbsp; </p><p>The actual improper mixing of the metal alloy is not my area of expertise and the change in direction of the etched lines is very baffling, as normal grain should be in onlu one direction. Could the various directions after etching be a combination of grain, rolling direction, and metal flow during the minting process?[/QUOTE]</p><p><br /></p>
