Looking again it maybe a die dent. I know this might sound strange, but a small contact on the outside edge of the die would make an incuse area on the die, when a coin is struck, the lower lip on the die that forms the rim shows a raised area on the coin from the die dent.

But on your coin it doesn't look that large. Also noted it is a die crack.
