Tetredrachm Greek

Can this be cleaned at all? And what’s it worth normally?

    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:

    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.
