<p>[QUOTE=&quot;GDJMSP, post: 438122, member: 112&quot;]Not really sure what it is you are calling slag, I assume you are talking about the raised bumps ? Now when I think of slag, it&#039;s melted metal that drops onto the surface. But with coins, that doesn&#039;t happen. Even with a cast coin a raised bump is a depression in the mold. Same with a struck coin only it&#039;s a depression in the die.</p><p><br /></p><p>As to what would be the difference between a die chip and slag - vitually none as they are both depressions in the die/mold. The only difference would be what had caused them. A die chip obviously is caused by a small piece of the die breaking. What you are calling slag can be caused by a tool mark or just a poorly made mold that wasn&#039;t smoothed out properly.</p><p><br /></p><p>A rusted die on the other hand causes raised bumps on the coin because the rust leaves small pits caused by the corrosion in the face of the die.[/QUOTE]</p><p><br /></p>
