<p>[QUOTE=&quot;desertgem, post: 2241977, member: 15199&quot;]The photo you show that seems to be your coin, hazily due to focus, show mechanical doubling, not true hub doubling that was used in 1969. The hub doubling was due to the working die being impressed more than once, unlike &#039;single squeeze doubling&#039; process used today. The working die had to be removed from the process between the hubbing process to soften the metal a little to impress deep enough. If when replacing the die for the second time, there was some movement, the secondary impression would not be exactly over the original, and when it was not noticed and used to mint coins a double image would result. </p><p><br /></p><p>Two things would always be obvious, first the combined image would always be a little to a lot wider than a normal one, since one image would be normal and the other partially covered, except for the doubling part.</p><p><br /></p><p>Secondly since it was pressed with the same force, it would be very close to the height, not one normal and the other a ledge, smear, etc. Below are 2 famous DDO, the 1955 DDO, and a 1972 DDO die 1. Notice how the two impressions blend in with each other because of the same height. Where the &#039;5&#039; and 9 cross over each other. This shows a true hub doubling. </p><p>&nbsp;&nbsp;&nbsp; And if you look at the CPG book illustration of the 1969S DDO, you see the same height relationship.</p><p><br /></p><p><img src="http://i141.photobucket.com/albums/r78/predcarn/195555date.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /> </p><p><br /></p><p>Same for the liberty in the 72, the &#039;L&#039; and other letters.</p><p><br /></p><p><br /></p><p><img src="http://i455.photobucket.com/albums/qq279/desertgem/197272d-1.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /> </p><p><br /></p><p>Good luck![/QUOTE]</p><p><br /></p>
