Well, I have a coin here. It looks like a BDC. Also it appears to have mint grease retained in the memorial, on the right side of it. The coin had faucet water run over it and, due to its condition, i took the liberty of lightly brushing the suspected hardened grease . The result being what you see. Its still there. I have 12 saved photos of the 30 that i just took. Here are 8. I hope i get the best ones, will put up the other 4 upon request.

the crack is a plating issue for sure.

the retained grease/debris, i'm leaning towards no. USUALLY, you can see actual struck through area alongside the debris, the few times i've seen debris actually still with the coin.
