I am thinking that this is a Feeder Finger scrape from the Feeder Fingers.
Errers and Varietys.

I still think it's Feeder Finger Damage from the Feeder Fingers malfunctioning and scraping the surfaces of the coins. I see this happen a lot on LSC's, especially from 2017. You can keep it as a good example of Feeder Finger Damage/Scrape.  Errers and Varietys.

So to the class I have a question:
"Why do the finger feeder damage show behind the shield and behind the rim and not through the shield and through the rim?" If you already know this answer, let the new ones think about it for a while and them them explain. Lets say under 500 posts can answer. This will help them learn something new or remind them of something they forgot.

 "Coop says under 500, now that doesn't mean 501." |

My guess would be the when the dies press the devises flatten the mark left behind by the feeder fingers. Wrong I'm sure!

Yes, you are wrong.
Let me give you a first clue: What does a die look like? How does it compare with a coin?
Second clue: What does it mean that a die is a negative relief and a coin is a positive? (See if this question helps answer the question?)

@coop, I believe I know now what you are getting at. It isn't from the feeder finger, this is coming from the die itself as it is pressed into the planchet. Meaning it is coming from a die that has stress cracks.

Getting closer. A feeder finger becomes bent. Probably from get struck when it was not out of the way yet:   This alteration of the feeder finger affects what (?) to cause these marks? Answer: _______________________________________________ |

@coop, because I do not know exactly how a feeder finger functions I am going to say that because the feeder finger is harder than a planchet the feeder finger actually damaged the die after the die struck it.

Correct. Now we are getting closer. If the damage is on the die, why does it flow behind the shield and the rim? Answer: ______________________________________________________ Clue: The die is a negative on a coin. https://www.coincommunity.com/forum...erse_Die.jpg |

@coop, because the die is negative relief, that is the only part of the die that came in contact with the feeder finger.

And what area of the die is affected. The devices (sunk into the die) or the fields? (outside portion)
