I got this in the junk box for 25 cents, it is around 18 mm in diameter. The edge doesn't look ground or clipped in anyway. If it is real, any idea on value or if I should sent to be graded.

The natural edge of the coin, seen in the bottom right of the first photo looks and feels the same as the rest of the edge. Maybe a little less uniform do to not having the collar, but it doesn't look shaved.
