Question for you: are the lines that you call scratches raised and stop at the devices?
If they are, those are not scratches, but actually die polishing lines. If two dies strike each other without a planchet between them, they create clash marks on the dies. Those marks can be abrasively removed from a die but fine raised lines are left behind. These lines are commonly confused with scratches. They are scratches, but on the die and not the coin. Posting a picture should give a definitve answer.
