I "think" it's because it was created by two separate stressing events..?

The chips & breaks formed from eventually falling out are created by an individual crack that splinters then comes back together, leaving an RIDB or RIDC that's already under direct pressure / incident within a singular event.. The one pictured has no such central pressure allowing for job completion..

Ok, I'm going to take a stab at Coop's question but only after reading up on the subject:

If this occurs in the process of striking blank planchets, at high speed, and a flake or die piece breaks off from the surface of the die, depending on where the broke piece comes from and comes to a rest, with the motion of the minting press, it is captured within or near the cavity that was created and subsequent strikes press it back into to die steel.

The Teacher deserves a day off, perhaps a day at the beach.
