<p>[QUOTE=&quot;Conder101, post: 1813729, member: 66&quot;]The problems with a study like this is 1, you really need to have fairly high grade coins for making comparisons.&nbsp; 2. I can see you requiring many shots of each edge.&nbsp; Every feature you want to compare really needs to be in the center of the shot.&nbsp; Because you are mapping a curved surface onto a flat plane the further you get from the center the more distorted your image becomes.&nbsp; For example your comparison of the S-67 &quot;round O&quot; edge to the S-18a and 19a &quot;oval O&quot; edges.&nbsp; Is it possible that the 18a and 19a have oval O&#039;s because the O is closer to the edge of the image and you are looking at it more &quot;edge on&quot; resulting in a foreshortening of the width of the letter?</p><p><br /></p><p>I can see you needing straight on shot of each letter of the edge inscription, and possibly also the space between each letter.&nbsp; Even then you have to consider slippage&nbsp; of the edge dies, or that the Castaining machine wasn&#039;t retracted fully between coins.&nbsp; Of course those two are more involved with the space between the beginning and ending words and not the spacing between individual letters.[/QUOTE]</p><p><br /></p>
