The coin has been in acid. As far as what you see it is a term called Pareidolia, it's kinda like when you see images in clouds.
Maybe, if I was sure I would not have asked for opinions. It's like seeing unicorns in the clouds. LOL thanks
The '41' effect you see is not on any font used for quarters in the Washington series, nor in that position in relation to the bust. It is damage IMO, Jim
That would be due to the acid bath it received. People do strange things to coins. One way to learn is to familiarize yourself with the minting process. Then when you see a coin you think is strange or different ask yourself, How could this have occurred in the minting process? Welcome to CT.
I agree that it's not anything. I would think if it were a true '41 over strike, you would be able to see some more in other areas of the obverse and there are none.
