What is this?

Got this out of a roll from a armored car delivery a couple days ago. It's very thin and the reeding is solid copper. No silver on the reeding whatsover. I'm not sure if this an error or someone somehow machined it at home. It's very precise in how thin it is all the way around. I haven't seen anything on
it. So any info is appreciated.

That coin got caught in a washing machine 100% for sure.
Damaged coin.
And the Reverse
That's weird as the washing machine usually affects both sides.
It is still a washing mach coin tho. Damaged.
Post-minting damage.
Interesting black rim. What about the washing machine causes that sort of damage? Coin stuck/rubbed by some rubber gasket?

The coins get stuck in the space between the rotating drum and its housing.
Gotcha. Does that make a distinctive noise as well?
PMD, could have been done several ways some intentional and some by accident.

Pmd, only worth a quarter
I have many coins that have gotten stuck in the washing machine and at first I thought the same. But the reverse is spotless of any damage I've seen with any of the coins stuck I the wash. This coin is very different.
Actually called a "dryer coin", although i've never seen a dryer coin look like that one. Usually dryer coins have wider and flatter rims with the details of the coin looking "soft" - not as sharp as the OP's coin shows. Looks like pretty uniform wear/sanding down for some reason but just wort a quarter (PMD)

"When they can't find anything wrong with you, they create it!"
I used to call these "dryer coins" until we got a brand new washing machine.
Our new washing machine kicks out one to these about once a week.
eBay is bombarded with these washing machine coins.
For some reason, my wife likes to put coins in the slot
It really doesn't matter if it was a washing machine, dryer, or some other form of abrasive PMD, the key takeaway is that there is nothing in the minting or die making process would produce a coin like that. So, if it couldn't leave the mint like that, it's nothing more than PMD
When trying to identify errors, you should never think "I can't explain how this damage occurred so it must be an error". There are a multitude of ways a coin can be damaged after it left the mint. You always need to explain how it occurred during the minting process. While members might be debating the cause of the damage, don't mistake that as a possibility you have an error. You do not.
If you plan to keep searching for errors, i would recommend spending time learning the minting process. The more you know, the less time you'll waste on PMD like this one.
I agree with PMD.... And what @Oldhoopster said is 100% great advice. Learn the minting process.... So many coins posted here as 'errors' are just obvious PMD. Cheers, RickO
It is damaged.
IF you think otherwise, please explain how that could have been minted that way.
