<p>[QUOTE=&quot;Scuba4fun777, post: 2668766, member: 75199&quot;]I agree that this drawing is not a perfect reference. Really, it does a better job of pointing out the main features of hub doubling than machine doubling. However, there is one main feature of machine doubling shown in the picture without actually being highlighted: the fine parallel ridges in the area marked &quot;flattened&quot;. These lines are indicative of the raised area(s) of the coin actually being moved against the rest of the coin by a loose die. It&#039;s basically the metal that&#039;s still in the die as the rest of the coin is forced away from it. </p><p>Ok. The picture was earlier today, but I don&#039;t think we&#039;ve hit a thousand words (yet?).[/QUOTE]</p><p><br /></p>
