Could you please post a photo of the entire obverse of the coin? Thank you. The reason I'm asking is, a deteriorated die also causes radial flow lines. The devices on a die are incuse and while it's possible for die polishing lines to show up in those areas, it's not that common.
They are radial flow lines on a worn die. Metal flows as a planchet is struck and will erode these features into the die. Note how they are radiating towards the rim
I don't know where this misinformed crap came from but THIS IS A TOTALLY IGNORANT STATMENT that needs to be corrected ASAP: "Die polish lines do no show up on the devices..." Anyone who looks at enough coins should know this is stupid!
Collecting Nut, posted: "They are not Die scratches but they are from a worn die. The name escapes me at the moment." Try "worn die radials."
More pic's please as I would like to learn from this example. I often mistake die lines for improper cleaning
I would like to see more pic's also what you have appears unique. I agree with John Wright opinion. Thanks for the post be safe
They must be several names for it but one thing it certain, it's not from due scratches. So far I've seen radial flow lines, flowlines and worn die radials but one thing we all said was a worn die.
Under a microscope just about all DIE STRUCK coins show the flow lines in the metal (radials). When they get large and obvious like the OP's coin, many call them "worn die radials."
