....Suggesting a "What Happened Here" forum, not to be confused with error coins, but as a challenge to answer what type of external damage caused a particular appearance on a coin ... ...I'll start with this 2017 D Lincoln ... ...looks like it was blasted, front & rear, with micro - bird - shot ... not much in the way of scraping to the coin, just these very tiny pits across the two surfaces ... ...what happened ...

Nothing to see here, just the usual quality of zincolns coming out of the mint.

A local plumbing business has a small enclosed sandblaster they use to clean rusty parts. That could create such a look. My wife has used a small sandblaster at art class for putting frosted designs on her glass pieces. Obviously the cent has PMD from something, maybe it was in a gravel road or tumbled in a gem/rock barrel.

Some of the pits have tails indicating it was also dragged a bit. Run over, flipped, run over again.

Quote: what's the oldest answer?. Unless you were there when the damage occurred, it's difficult, if not impossible, to determine what caused the damage. Whatever the cause, it's just a damaged coin.

livingwater:..." ...sandblaster they use to clean rusty parts..." ...doesn't look like sandblasting effect ... but good guess ... John1..."It was lying on a cement sidewalk and people walked all over it?''... ...close to something like that (it occurs sort of evenly on obv. & rev. ... doesn't look like foot traffic damage / random scraping...), ...keep thinking ... Cujohn ... "Nothing to see here, just the usual quality of zincolns coming out of the mint.' ...    ...ain't that the truth! ...

My guess is....  ....a cent inside a folded piece of 80 grit sandpaper wrapped in leather and struck by a blunt object on a firm surface. Don't see how you guys could have missed it.

It's a pity  the coin has ended up in this pitted condition.

Whatever happened to it, it wasn't outside in the rain for very long after it happened. There's virtually no zinc rot that I can see; it all looks like physical damage, rather than corrosion.

...loonielewy: "My guess is........a cent inside a folded piece of 80 grit sandpaper wrapped in leather and struck by a blunt object on a firm surface..." pretty good assumption ... most reasonable guess so far ... I'll try & duplicate that method & see what happens ... may I borrow a penny?...
