This coin has two possibilities; One is that someone has altered the coin after minting, such as coating it with Mercury, ETC. A related possibility is that the zinc base coin lost its copper plating, or was never plated in the first place. This type of coin is worth only face value. The second possibility is that it is a misstruck coin. This type of error in minting is called 'Wrong Planchet'. The only planchet that a penny can be mistakenly minted on is a dime planchet. These are extremely rare and are worth $250.00.
