I found 2016-D Fort Moultrie several months ago and held on to it for further research into the multiple scratches on the obverse. In the meantime I came across several more quarter examples with similar scratches and 'line of dots' including two new quarters in bank rolls, a 2019-D Lowell (an ender with some roller damage) and a 2018-D Apostle Islands. The Lowell is likely uncirculated prior to this find. My research turned up this article in Coin World, showing a 2002-P Indiana with similar looking mint damage although even more profound and on both sides of the coin. I have 5 quarters in total with these scratches. Pics of 3 attached, the other two are a 2007-P Montana on reverse and a 1981-D on the obverse. All of these coins have one or more deep gouges and/or skipping lines, and they all appear eerily similar (with possible exception of the 1981-D I included). For the 2002-P example see: https://www.coinworld.com/news/prec...inghouse--new-term-needed-for-error-type.html Please feel free to chime in as to the possibility of this damage being caused at the mint or if simply p.m.d in your view and how you arrived at your determination. And tell us if you've ever come across coins with a similar type of gouging, or potentially know how this might have occurred in the mint in the first place (if a mint error)?
I read the article, and I don't think your specimens are the same. However, are you aware that the author of that CW article is a member here? @mikediamond - Has there been any further follow-up to your initial article? Chris
Some of your coins have severe scratches on them, and one has contact with the reeded edge from another quarter. I either see PMD scratches, or no marks/lines on some of the other photos. I read the article you linked, (had forgotten it), but I don't see anything like what is described on your coins....just my view.
