<p>[QUOTE=&quot;19Lyds, post: 916717, member: 15929&quot;]Machine Doubling is quite common on the Kennedy Half&#039;s and you really need to post pictures before submitting anything. </p><p>&nbsp;</p><p>Examples:</p><p>&nbsp;</p><p>Below is a doubled die (which also has some machine doubling on it) True doubling is the Red Arrows while the Machine doubling is the White arrows:</p><p>&nbsp;</p><p><img src="http://i164.photobucket.com/albums/u8/lcl1119/Kennedy/Misc/1972-DKennedyDDR-01AD.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p>&nbsp;</p><p>While the coin below is not.</p><p>&nbsp;</p><p><img src="http://i164.photobucket.com/albums/u8/lcl1119/Kennedy/Misc/005W.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p>&nbsp;</p><p>As incredible as it looks when you pull back:</p><p>&nbsp;</p><p><img src="http://i164.photobucket.com/albums/u8/lcl1119/Kennedy/Misc/004W.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p>&nbsp;</p><p>It&#039;s still NOT a doubled die. This phenomenon occurs when the coin is moved before completely clearing the die at ejection time OR when the press falls out of alignment with loose screws due to the incredible amount of force that is used to mint these large cooins. Very much similar to taking a rubber ink stamp, placing it on paper and then moving the stamp before it is picked up from the paper.</p><p>&nbsp;</p><p>A doubled die occurs when the die is created and has been improperly aligned with its working hub prior to rehubbing. In the past, all dies were hubber at least twice to bring out their full relief. Working Hubs are what Working Dies are created from and the process is:</p><p>&nbsp;</p><p>Galvano to Master Hub to Master Die to Working Hub to Working Die.</p><p>The Working Hub to Working Die requires precise alignment to avoid creating a doubled image on the working die.</p><p>&nbsp;</p><p>When you get a chance, please post pictures for a better determination or compare the photo&#039;s I;ve provided with what you have.[/QUOTE]</p><p><br /></p>
