<p>[QUOTE=&quot;iPen, post: 2063088, member: 69760&quot;]I posted this within an unrelated thread and I think it would be better to dedicate a new thread for this topic because I&#039;m still confused. After reading about mechanical doubling on Wexler&#039;s site (link below) and here on CT, I&#039;m confused as to <u>why there isn&#039;t more doubling throughout the coin on almost every single design element <i>most</i> of the time</u>. This question is different from how to identify MD (e.g. flatness of doubling, no rounding and very low relief, etc.).</p><p><br /></p><p>After reading about MD, the parts connected to the die(s) are loose, which causes the MD to occur. The planchet itself is secured by a collar, so the die is what&#039;s doing the moving, causing the doubling. So, if the entire die is what&#039;s rotating (pivoting from the center and not the edge) and/or shifting in one direction, then at almost every conceivable possibility, <u>shouldn&#039;t MD be evident on every single design element</u> (e.g. the portrait, words, date, MM, monogram, etc.)? Why is it that many if not most of the MD that&#039;s seen (at least by me) only on just the date, or a combo of the date, MM, and letters. - it seems to be restricted to just those features of the design (although Wexler does provide an example of MD on Kennedy&#039;s portrait).</p><p><br /></p><p>Unless the die pivots at the edge, then it would hit and damage the collar and the rim of the coin would be flattened (always I presume) and cause doubling on a small section of the coin (but every coin with MD in a small section like just the date has an uninterrupted, full rim)... or unless the planchet itself gets struck twice, and pivots from one edge of the planchet off the collar, then MD limited to just the date, MM, letters, etc. makes sense. Is one of these possibilities described in this paragraph the answer?</p><p><br /></p><p>I feel like there&#039;s something I&#039;m missing here. Thanks in advance for any clarification!</p><p><br /></p><p><br /></p><p><br /></p><p><a href="http://doubleddie.com/144822.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://doubleddie.com/144822.html" rel="nofollow">http://doubleddie.com/144822.html</a>[/QUOTE]</p><p><br /></p>
