Just a guess on this. I believe it&#039;s PMD.</p><p>the 1920&#039;s something (1926?) cent could be roller lines, but could be done by an abrasive also there appear to be lines that don&#039;t fit the rolling pattern direction, but that could be due to two sources of the lines that are seen, one of roller lines, and one of abrasions. I&#039;m feeling PMD here also.</p><p><br /></p><p>Again, I am not trying to offend anyone on here or rag on people&#039;s coins, just giving my opinions on what I&#039;m seeing and what I know to be on this topic and wanting to share. Please don&#039;t take it personal. I can be wrong, maybe I am, just my 2 cents. I spent a long time on all these planchet issues to figure out the differences of these planchet issues, and in the end, really none of it is value adding, since it&#039;s all &quot;pre-strike&quot; or planchet preparation problems and not really &quot;mint errors&quot;. the added value might come if you have an auction with a few woodie collectors that are looking for a certain toning pattern for their set that will pay extra to fight for it and bid it up. My opinion, that will happen with any coin if a number of collectors bidding at an auction consider a coin to have exceptional eye appeal.</p><p>Anyways, my 2 cents, take it for what it&#039;s worth! Hahahaha[/QUOTE]</p><p><br /></p>
