What is the value of a 1972 penny that is silver in color?

Most likely, your coin has been plated with either zinc, silver, or nickel. This novelty item has no added collector value. The coin may have been dipped in mercury, a common "fun" practice in the 60's and 70's. That would leave a coin with a similar color to other coins, but could be dangerous to handle due to mercury poisoning issues. If there is a coin show in your area, you can take it there for free first-hand examination by the dealers. You may be able to find a local show by clicking on the Related Link, "Coin Shows." This coin could be one that was struck on the wrong 'Planchet'. If it is, it could be worth up to $225.00.
