<p>[QUOTE=&quot;mikediamond, post: 45277, member: 1859&quot;]Off-center strikes almost inevitably show no reeding.&nbsp; That&#039;s because the planchet is positioned above the collar during the strike and depresses it during the strike.&nbsp; Often the collar isn&#039;t even deployed during an off-center strike.</p><p><br /></p><p>There is one exception to this general rule.&nbsp; An off-center planchet can be forced completely into a collar that&#039;s frozen in the &quot;up&quot; position.&nbsp; What you have then is an area of full collar contact at one pole and a complete absence of collar contact at the opposite pole.&nbsp; Such errors have been termed &quot;ram strikes&quot;, since the coin is rammed into the unyielding collar.&nbsp; The face struck by the anvil die has a rounded shoulder while the opposite face shows a vertical flange.[/QUOTE]</p><p><br /></p>
