I think it is die abrasion/polishing. John1  |

Thanks everyone. I think I agree die abrasion/polishing is the most likely cause.

Some interesting trail lines on the reverse around States Of America which clearly supports the die polishing theory.
Don't see this one listed on Traildies.com, so if they're taking submissions they might like to see your photos.

Good catch on the trail lines, I missed that. John1 |

Looks like an extreme die scrape, very cool looking! LINK https://www.error-ref.com/die-scrapes/ Noticed the trails too, very extreme at the "F" but feel the two are unrelated, just coincidence in my opinion. -makecents-

Dearborn, I could be wrong but do not think this is feeder fingers damage. Not the typical direction.

No it is not the usual direction but I have seen it this way. The quote I put up was taken directly from your reference and clearly identifies FFD in it

Funny, I just did an internet search for this and came across a different coin forum where they are discussing very similar areas on Mercury dimes and having the same back and forth: Feeder finger damage/die abrasion that is polished off, vs die clash marks that are polished off. They don't appear to come to a conclusion. Then I went to look at Jefferson nickel die clashes and found this, which shows a clash mark right at the same location. And it is on a 1966 SMS. Interesting! http://www.maddieclashes.com/adc-5c-1966-01sms/ |

You bring up a good point Data, (however) if the clash was so bad that if it had to be polished so deeply it that spot, where is the rest of the clash that 'should' also be evident on this coin? (Also) I have never seen polishing lines that were done by a mint worker that had such perfect perpendicular scratches on the die. Take a good close look at the very first image.

@Dearborn, that's true, there seems no evidence of a clash elsewhere on the coin. It is just that the location lined up so well with this picture of the nickel on maddieclashes.com. If you've seen feeder finger die scrapes/abrasions with vertical lines like the ones on my nickel, then I am thinking that is it. Here's a snippet of the maddieclashes nickel and of the Mercury dime with a similar spot with vertical lines within it.   |

Normally we will see FFD at an angle in regards to the orientation of the coin being struck, but sometimes we see them straight vertical and horizontal. I found an old topic from Coop (back in 2019) that shows FFD from many different angles (including from straight down too. http://goccf.com/t/336856 |

I agree with the die abrasion.
