<p>[QUOTE=&quot;huntsman53, post: 509640, member: 1242&quot;]Doug,</p><p><br /></p><p>When the Dies are firmly seated against the planchet and the striking process is near completion, then that hole is firmly filled not only with the incuse details on the Dies but also the relief details on the nearly completed, struck coin. At this point, there is no hole per say for the grease or oil to flow into and the details on both the Die and the nearly completed coin which cross the Die Polish lines at right or left angles are the obstructions to the flow. These obstructions which sort of act like dams on a river, may not obstruct the entire flow but they obstruct enough of the flow to cause the grease or oil to exert pressure on the already created pressure ridge lines which run parallel with the Die Polish lines...thus the squiggly lines.</p><p><br /></p><p><br /></p><p>Frank</p><p><br /></p><p><br /></p><p><br /></p><p><br /></p><p>Frank[/QUOTE]</p><p><br /></p>
