<p>[QUOTE=&quot;gatzdon, post: 208583, member: 8247&quot;]Matching a missing inscription to a mint will require forensics.</p><p><br /></p><p>If you read nothing else that I write here, read this.&nbsp; If you find a Denver with a missing edge, go back where you got it and buy the whole box and save them.&nbsp; Then seek out groups who like to match coins up to the dies that manufactured them (like varieties and what not).&nbsp; Invariably, unless your coin was the first one struck with a new die, it will have marks transferred from the die.</p><p><br /></p><p>It could take some serious time, but in some cases, you could be able to find another coin in the box that can be matched up to yours.</p><p><br /></p><p>I have a philly with the missing edge inscription and lucky me, it has a die clash.&nbsp; thanks to n_sandler4 for discovering his and starting a thread or I might have missed mine.&nbsp; I am now going through several boxes to try and find another with the same die clash.&nbsp; If I find one, I figured it would be a nice addition to my collection to be able to prove which mint mine came from, even if it is a philly.</p><p><br /></p><p>I imagine a Denver with a matched coin would fetch a small fortune as those probably got out of the mint the same way a blank planchet does.&nbsp; </p><p><br /></p><p>I have a theory about the philly coins and it postulates that they in fact did go through the edge inscription step, meaning that number in circulation is dependent on how long the equipment ran unnoticed (I believe the rate is about 750 coins per minute.&nbsp; An hour would be a reasonable guess without any further input from the mint putting the total in circulation at around 45000)</p><p><br /></p><p>There are a number of philly ones with a starburst pattern on them which I believe is due to a contaminate on the coin being spun off during the edge inscription step, then the contaminated surfaces not accepting a proper antioxidant coating.&nbsp; While this would be enough to reasonably assume that the coin came from philly, it&#039;s not enough to prove/disprove it as it could happen at the Denver mint also.[/QUOTE]</p><p><br /></p>
