CoinHI Pillar of the Community United States 2736 Posts	Posted 08/20/2021 03:04 am This does show plating blisters and split plating errors. The other, larger marks I'm not sure about. The copper layer appears stripped away. It doesn't look like PMD to me but open to opinions. "Pride is yoked with callous behavior, as humility is with compassion."

John1 Moderator United States 56855 Posts	Posted 08/20/2021 04:20 am I think the copper plating "flacked" off during the minting process. John1 Report this Post to the Staff

Eagle_Eye Valued Member United States 55 Posts	Posted 08/20/2021 10:54 am It looks like a scrape to me. These coins with these plating issues intrigue me. I get the dust factor and those are easy enough to distinguish. However, sometimes you get lines of blisters, like under Abe's nose. One of my thoughts on these are from clash removal. Too aggressive polishing and they reduced the field just enough below its normal height that it caused unintended design difference and the plating didn't adhere to the now slightly raised design thus causing the gases to be trapped in the slight depression on the Die. Just one of my theories on plating blisters. Fresh roasted Java and a great Sativa and you'll see funny things too! EE Report this Post to the Staff
CoinHI Pillar of the Community United States 2736 Posts	Posted 08/20/2021 12:00 pm The area above the large zinc exposed strip looks more like a struck through or stress area in the plating. There is a similar looking area to the north which I point to. "Pride is yoked with callous behavior, as humility is with compassion."

CoinHI Pillar of the Community United States 2736 Posts	Posted 08/20/2021 11:22 pm Thanks for the feedback! Plating debris bubbles flaking off is where I'm leaning.
