Just looking at the northern lights grooves and the tool marks
being in the deepest part of the groove, that would be a raised
part of the die above the field. The tool would file across the
raised northern light ray and be transferred to the coin face,
inside the ray(s) and to the adjacent field where the file marks
end.
Trying to recreate the sequence of events in the run up to the
strike to get this result.
Thanks for the replies. Confirmed tool marks.
