Thanks for the responses from Levelsofmadnes and Coop.
This has morphed into two questions about this coin now and I am adding a couple more photos.
So first question was about the hit on the B in LIBERTY and it looks like consensus is it's PMD
Second question is wether this is a WH/DD variety and which one is it. I'm guessing WDDO-003 over WDDO-006 because of the location of the die chip on the shield above the U R in PLURIBUS seems to be closer to north of R than north of U. I can see no other markers on this coin though so this is very confusing plus I'm new to this. Thanks for any help.
