Yours is more of a corrosion issue. The OP's coin loolks like it was placed under a table leg to keep it steady.
You're better off searching wheat penny rolls. Found many errors that way. Takes a while, but who knows, some people never notice a major error.
It used to be against the law to burn or deface the flag or money but the 60's changed all that... To bad in my opinion!
money gets damaged all the time. People may leave it in their pockets, do their laundry have it fall out and bypasses the lint trap, and gets stuck in the drum. rolling around, wearing down, etc. Drop in a dirty parking lot and gets run over; dropped on the ground gets buried, the PMD is limitless. Plus add all the people that use coinage for artwork, jewelry, etc.
...and you will never see one exactly like that again, because it has been uniquely damaged somehow, someway. You would have a very difficult time trying to repeat the damage in quite the same way. Just a worn, damaged quarter...Spark
As already stated, PMD, Post Mint Damage, meaning it happened after it left the mint, so not an error, just a messed up coin. Seeing that you have been a member since 2018, you should have an idea of what members here expect. It would be helpful if you checked you photos before posting as they are very blurry, but still easy to tell it is just damaged. Here is my standard suggestion when it comes to photos. You should always post in focus FULL IMAGE photos (after you upload your photo, two buttons appear: Thumbnail and Full Image, click Full Image and your photo appears full size on your post and is easily enlarged by clicking on it. While it isn’t always necessary, it is nice to show both the obverse and reverse, even if your question is just about one side. Members can often give more valuable information having both sides to evaluate. Crop out superfluous background so just the coin shows, and post photos with correct orientation so members don't have to turn their computer in some awkward fashion to view it properly. Add close ups of areas you have questions about and make your questions as definitive as possible so we know what you are asking for. And try to have the best lighting possible to show the most favorable photo of the coin. Hope this helps in the future. Good luck.
Appears to have been caught in some type of equipment. Definitely a type of mechanical abrasion, maybe over a considerable amount of time.
