Ok class: Why doesn't this interior die break fall off the coin?
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..
