Parts of it looks like a hard PMD strike, but others parts look like it happened at the mint. What do you think?
Upper part looks like it has raised metal. The lower part seems to not have any. Hard to tell, though. Can you get some more photos of the area? Perhaps take them with the coin “upside down” so you’re looking at it from new angles. Appears to be raised metal, marks commonly seen when one coin falls on another. Cannot see raised metal here, but the lower part could be raised metal.
The design definitely looks like a reeded edge. Looking at the coin again it has contact marks in the area. Arm, breast, and flag. Probably just PMD.
