It's definitely
something that isn't
PMD. Really interesting coin.
There's a lot going on with that die pair. There is fairly heavy die clash polishing and some post-polishing additional die clashing. There are quite a few significant surface die cracks and a few deeper cracks. The cracks SE of the mm are also interesting. Overall, this die pair was working long past retirement age.
One of the surface cracks on the reverse meanders from 9 o'clock to 3 o'clock through the Memorial. It looks like it is nearly coast-to-coast, but not deep enough to affect the devices. Could the lower of the raised lines in the bay be part of the long surface die crack?
The upper line sure looks like it is either a
DDR or possibly a deep die gouge.
