Lincoln cents have never been struck in silver. They're made of copper-plated zinc. That leads to at least 3 possibilities:
> Your cent was struck on a dime blank. If it's the same size as a dime, you have what is called an "off metal error". These are valuable but you would need a professional appraisal.
> Your cent was struck on a normal zinc blank, but was never plated. If there is no trace of copper showing, it might retail for as much as $100.
> Someone dipped the coin in acid to remove the copper plating. In that case it's a damaged coin worth 1¢
In any case it would need to be authenticated by someone who specializes in error coins to rule out tampering or damage.
