<p>[QUOTE=&quot;mikediamond, post: 4306508, member: 1859&quot;]Here&#039;s another reason why this hardened die fill might stand above the level of the surrounding, unobstructed die-struck design.&nbsp; If the superficial layer of a thick coating of die fill came away from the die face during retraction of the hammer die, the upper surface of that layer would lie above the surrounding design.</p><p><br /></p><p>One error I&#039;d love to see is a full coating of die fill that stuck to the coin as the hammer die retracted.&nbsp; The outer surface of that layer should carry a cast of the die&#039;s incuse design (the mold), and the details of that cast should occupy a plane above that of the coin&#039;s die-struck design.&nbsp; This is different from a layer of die fill that falls on a coin and receives a strike that receives an impression.&nbsp; In that case, the raised design would occupy the same plane as the normal design.&nbsp; I haven&#039;t seen an example of such an error either, in part because typical die fill is too hard to take an impression or, less often, is too soft to preserve an impression.&nbsp; So that&#039;s two error types I need to keep an eye out for.[/QUOTE]</p><p><br /></p>
