CoinDude69 New Member United States 36 Posts	Posted 02/23/2026 5:26 pm pulled this out of a can piggy bank. 17 cents. 7 pennies and this dime that has an almost penny sheen outside the natural dime coating. the last two pics kinda show the "browning" of the dime better imo could this be a greasy strike through? or just some PMD? thanks Report this Post to the Staff

Rocky B Valued Member United States 109 Posts	Posted 02/23/2026 5:37 pm sorry, the "spiked" chin error is probably just PMD. Report this Post to the Staff

Errers and Varietys Bedrock of the Community United States 73698 Posts	Posted 02/23/2026 6:55 pm It's environmental damage ( PMD). Liquid or something might have been spilled on to the coin. Could have been a cup holder coin. Doesn't really matter, since it's just damage and not an error. Here's what a real Struck Through Grease coin looks like. Areas will be either weakly struck or gone from the Grease Fill. https://www.error-ref.com/struck-th...-grease-oil/ Errers and Varietys. Report this Post to the Staff
