Unfortunately, and especially IF you are using AI on google (or anyplace else) you will get a LOT of false answers.
The way AIs are programmed is to scan websites and "average" what it finds to give an answer. It cannot discern fact from falsehood. And it is a verifiable fact when it does not find a specific answer to match it will do what Ai programmers actually call "Hallucinate."
It will make up an answer with no basis in anything verifiable b/c the programmers put more emphasis on it being sociable than factual.
Ask it mintage, ask it to compare verifiable data (such as what year did the US make the most quarters?). But as soon as you ask it to identify, grade, determine if something is a doubled die, etc., you get a chance ot 75% correct answers. Anything needing an opinion going to bring questionable answers..
You have a damaged coin. We see this exact type of damage frequently .
More important is understanding until a person does a good study of what the machinery at the mint can accidentally make when it goes wrong, then that person should realize they have a very slim chance of actually identifying a mint error.
Social media and
ebay say just look for something odd. The con hobby knows when people don't know specifics of what to look for then the millions of damaged coins people WILL encounter end up tricking them.
