Thank you for sharing these good photos.
These look like contact marks, possibly from the reeded edge of another quarter.
Agree
Just damage from contacting another coin. Probably from the bag they were shipped in.
Also please do not use screen shots, they are too pixilated to see detail clearly.
More double D's
In this case, D is for damaged.
Mint errors occur at the mint during the minting process. Once that process ends, anything that happens to the coin that changes its appearance is considered post-mint damage (PMD).
When you're looking at an unusual coin, assume it isn't a mint error, as the reason errors command premiums over face value is because they are rare. Thus, most of the unusual-looking coins you find are not going to be genuine errors. Then go thru the minting process and see if what you're seeing could have happened during that process.
Learn about the minting and die making processes here: https://www.usmint.gov/learn/production-process
Once you understand those, ask yourself what part of those processes could have produced what you see on your coin.
