Really nice precud. Really thick and all the way to the rim!
It's amazing that this part of the hammer die was still in place when your coin was struck. I was under the impression that since the obverse was the hammer die and pulled away from the anvil (reverse) die broken pieces of the die would fall out. Something about the break must have "locked" that piece in place.
