Brandmeister Pillar of the Community United States 6452 Posts	Posted 04/02/2026 1:03 pm (original title: 2018-p Dime: Flawed Planchet, Feeder Finger Damage?) Ran across this in a coin roll. The unevenness seems restricted to the fields on both sides of the coin. That made me think it might be die damage. If it were the planchet itself, shouldn't the anomaly stretch into the devices? However, under magnification, the anomaly seems more like pitting or surface damage than raised scratches. Wouldn't die damage result primarily in raised features? Bit of a puzzler, this one.

Errers and Varietys Bedrock of the Community United States 73628 Posts	Posted 04/02/2026 1:19 pm It sure looks like Feeder Finger Damage, along with a Field Restricted Struck Through on the obverse and reverse. Errers and Varietys. Report this Post to the Staff
Brandmeister Pillar of the Community United States 6452 Posts	Posted 04/02/2026 2:24 pm Yeah, you are probably right about that! Thanks, E&V. =) The ejector scrape article below shows a reverse that is struck through gritty paste. Looks very similar. The second article on field restricted struck through errors has good text but not many images. I hadn't realized that feeder scrapes and struck through grit errors often happen together on opposing die faces, because the malfunctioning feeder fingers are spreading gritty paste. Makes sense, though. A gunked up machine probably has all sorts of problems delivering the planchet into the striking chamber. https://www.error-ref.com/feeder-ejector-scrapes/ https://www.error-ref.com/field-res...ough-errors/ Report this Post to the Staff
