Appears to have the impression of a backwards ONE along the rim. Not super well versed in this kind of marking so any help is much appreciated!
Np your very welcome... i can see why you believe to be the lettering. When you post hit the "in full " button. That way your image is bigger and we can get a better look. Thanks
A reversed ONE on the rim would indicate damage. Another coin was pressed into yours leaving the reversed impression. It's not an error.
Here's a link to explore - Search Results for “rim” (error-ref.com) Part VI. Striking Errors: Weak Strikes: Rim-restricted Second Strikes If you note, your coin is in the reverse and looks incuse. @Oldhoopster has you steered in the right direction.
