..right....it looks to me like a casting seam now i can see it.. just from what i can see.....i'd say it's fake...you'll have to remove it from the cardboard window and take a pic of the edge for better clarity....
After seeing these new photos my first thought is this coin is a cast copy, a fake. My second thought is you should return it for a full refund.
What are the chances that it's not a fake and is genuine. The wear and the strike seems genuine to me. I paid for the item on a prepaid card so getting a refund will be tricky. And why is the reverse triple striked?
