Lydia --
NEVER CLEAN A COIN. CLEANING RUINS VALUE.
There are professional "coin conservation" services that many collectors find acceptable. The work is done by museum curators, not by people like us. See, for instance:
https://www.ngccoin.com/ncs-conservation/
The off-center strike and lack of detail will lower value compared to your other Athens coin.

Paul Richards Okay thanks for letting me know. I certainly wouldn’t want to devalue it.
