The coin does have a nice ding in the rim but what looks like a bezel is the way D mint indians are made. THey have that extra rim around the periphery. Most 1914d and 1925d have that. The photo highlights it.
My understanding that the ring was the result of worn dies and the dies could not be polished because of the inverse dies. I am not sure how or why worn dies created the ring that is seen on the $2.50.
