IMO your coin show Die Deterioration Doubling. Read the 4th paragraph down on the following site: http://doubleddie.com/144843.html About doubling showing on both sides of the letters. (on PLURIBUS).
I can see where one might initially get excited about seeing this. It's a dramatic example of DDD. You're looking in the right spot though!
At the same site as Thomas posted a link to you can also read up on hub doubling which is what you want to find.
Man! It took a hard hit on the rim. That would have been a vary good example to keep in a 2x2. Still it I guess..
