<p>[QUOTE=&quot;Lehigh96, post: 975505, member: 15309&quot;]I do not accept that as a fact until you can prove mathematically that the striking pressure is lower simply because the collar is missing.&nbsp; Based on the images, it appears that the striking pressure is higher at the centers of the die and the loss of pressure becomes evident at the rims of the coins.&nbsp; That indicates that there is a pressure gradient across these off center struck error coins.&nbsp; </p><p><br /></p><p>Furthermore, posting a couple of error coins does not disprove that planchet irregularities are remnant at the high points of weakly struck coins across many series of US coins.&nbsp; The Jefferson Nickel is one series plagued by weak strikes.&nbsp; However, the planchet irregularities were such a problem that they even appeared on well struck Jefferson Nickels.&nbsp; Here are some examples:</p><p><br /></p><p><img src="http://i117.photobucket.com/albums/o59/ACPitBoss/Jefferson%20Nickel%20Registry/JeffersonNickel1945-PPCGSMS65FS-1.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><img src="http://i117.photobucket.com/albums/o59/ACPitBoss/Jefferson%20Nickels%20Full%20Steps/JeffersonNickel1943-SPCGSMS67FS1.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><img src="http://i117.photobucket.com/albums/o59/ACPitBoss/Jefferson%20Nickels%20Full%20Steps/JeffersonNickel1944-PNGCMS675FS4Lab.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p>By all accounts, these three Jeffersons are well struck.&nbsp; Each coin has full steps and Monticello displays all doors and windows.&nbsp; The hair detail is strong on each coin yet we still see the quintessential surface roughness that plagued the jaw line of the Jefferson series.&nbsp; </p><p><br /></p><p>Now Doug, take a look at the last Jefferson, the 1944-P.&nbsp; There is a distraction of note on the collar of Jefferson&#039;s coat.&nbsp; It is small but sharp and well defined.&nbsp; Other than that lone mark, the only other relevant imperfections on the coin are the planchet flaws on the jaw.&nbsp; Compare the two!&nbsp; The planchet flaws are shallow an indistinct.&nbsp; Not to mention there are a multitude of them in one are of the coin, a coin that is otherwise nearly perfect.&nbsp; So how exactly does that happen.&nbsp; Here is your previous explanation.</p><p><br /></p><p><br /></p><p><br /></p><p>Well to use your words, I ain&#039;t buyin it.&nbsp; How many examples will you need to see of high grade Jeffersons with this phenomenon on the cheek before you realize that the only way those marks can appear is that they are remnants of the planchet surface.&nbsp; This same effect can be seen on just about every year of the Jefferson series at the exact same spot of the design with the the same general appearance.&nbsp; When you add it all up, planchet flaws is the only explanation that makes any sense.[/QUOTE]</p><p><br /></p>
