pnewman Valued Member United States 58 Posts	Posted 04/10/2023 01:24 am So I've seen a few examples of grease coins and came across this guy and have an inkling it possibly might be? Any thoughts and information on how to better spot grease aside from PMD? According to it being "sanded flat" that's literally impossible with 0 visible wear damage to any other parts of the coin whatsoever. LIBE would have easy visible sanding damage.

ijn1944 Bedrock of the Community United States 19119 Posts	Posted 04/10/2023 08:08 am I'm thinking post-strike damage. May have been slid across 'smooth' concrete a few times (wearing away high surfaces) early in the coin's life, then in general circulation for many years afterward. Report this Post to the Staff

coop Bedrock of the Community United States 62064 Posts	Posted 04/10/2023 4:27 pm If the weight is ligher than normal, it may have been sanded. But if it is an altered coin, then it is a face value now. Report this Post to the Staff

pnewman Valued Member United States 58 Posts	Posted 04/10/2023 8:24 pm If sanded flat, I put a razor edge along the coin, how does the sanded parts alone sit lower then every other part of the coin which has no sanding damage? Would make sense if the sanded was flush or raised from the rest of coin still but so called "sanded parts" on each side sit lower then rest of the coin with no visible damage? As a metal worker this would make no sense. Report this Post to the Staff
JimmyD Bedrock of the Community Canada 21586 Posts	Posted 04/10/2023 8:30 pm It doesn't really matter exactly how it happened, the fact that it could not have happened during the striking of the coin defaults it to PMD. Edited by JimmyD 04/10/2023 8:31 pm Report this Post to the Staff
pnewman Valued Member United States 58 Posts	Posted 04/10/2023 8:30 pm As a specialty metal fabricator dealing with .060 tolerances and sanding and grinding metal every day. To have the middle of a coin completely sanded with 0 damage to the any parts is almost impossible. Report this Post to the Staff
pnewman Valued Member United States 58 Posts	Posted 04/10/2023 8:34 pm Well "no matter how it happened" there would be sanding damage on higher surface areas of the coin according the logic you guys are making? Report this Post to the Staff

pnewman Valued Member United States 58 Posts	Posted 04/10/2023 9:24 pm I run a 2" die grinder and a dremel, grinding, sanding, buffing, and polishing on metals almost everyday. The idea of someone sanding flat a Penny's bust and memorial with a die grinder and also leaving 0 evidence or damage of this idea is just crazy to me but I guess that's it.
