Hi, I am just wondering what this might be. There is an area of metal on the reverse above the left of the memorial that is very smooth and shiny and doesn't look like damage. Any ideas? This coin was in a 1966 Special Mint Set that had been opened, but I think it is original. Thanks

Yeah, mine too. it is off to the side and has some grooves in it, I have never seen it as a broad swipe of it before.

That is really amazing looking. I know this will sound stupid but, could it be a grease issue?
I look forward to reading all the posts on it.
Thanks CC

Maybe polishing off a clash?

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.

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.

LINK https://www.error-ref.com/die-scrapes/ Thanks Makecents, I think so too Die scrapes created by the feeder fingers (*which was my first thought up above) The following quote is taken directly from Error-ref: Quote: Definition: Die scrapes are a form of die damage generally caused by the feeder/ejector scraping across the die face. While the anvil die is most commonly affected,

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/
