Looks like to me there was an issue with a tilted die and it made a fin on the outside edge of the 8:00-10:00 area. The fin has flattened and now looks like something going on with the rim. But because it is flattened it is now a spendable coin. If the fin was still showing then it would have been more interesting.


This is now flattened on your coin removing a premium for this.
