I can see a lot better in that pic. thanks!
One of the bits does look completely round, and if the edges are not sharp, it could easily be an air bubble on the surface which has broken and collapsed under annealling. But if all the other little white things are also dents, and they're on the body, not just around the edge of the base, then it is more likely to be damage.
Maybe it got propped inside something at one point in time?
