I was looking at a stack of 19 dollar coins on my desk, and I decided to sort them based on design and mint mark. I noticed on one of the John Adams dollars, where there should be a large gap between "2007-P" and "E Pluribus Unum," the 2007-P was right next to the motto, so it read "2007-PE Pluribus Unum." Also, the gap between the second dot and "In God We Trust" was larger than normal. Here's what a normal edge looks like: * In God We Trust * 2007-P E Pluribus Unum Here's what the suspect edge looks like: * In God We Trust * 2007-PE Pluribus Unum My question is if this is something that's worth getting certified by one of the third party graders and slabbed? I've never seen this discrepancy with any edge lettering before, so I wonder if I have a legitimate error coin in my possession or not, and I don't want to waste time and money on certifying what turns out to be a common occurrence on our coinage.
you can click on the link I'm adding here and read about the type error your coin has. http://coins.about.com/od/errorcoinsdievarieties/a/edge_lettering_3.htm
It appears to be a edge lettering misalignment, made during the manufacturing process. This apparently happened on the other 2007 presidential dollars and necessitated the extra dot after the date and mint mark for the 2008 presidential dollars.
you are right and this same thing can be randomly found on other types of the presidental dollar coins. I think what happened to these coins was that some of them slipped a few notches while in the edge lettering machine.
