A completely unplated cent can be worth up to $100 at retail. However you'll need to have it authenticated to ensure that it wasn't altered, for example by dipping in acid to remove the plating.

Traditionally, the US penny (or, more properly, the US one cent coin) has been made of copper or copper with a small amount of zinc (except in 1943, when it was made of steel with a zinc coating). During 1982, as the price of copper meant that the "melt value" of the coin was more than one cent (that is, it had more than one cent's worth of copper), the decision was taken to produce the penny out of a cheaper metal - zinc. A coating of pure copper (equal to 2.5% of the total composition of the penny) was added so as not to change the appearance of the penny.

All pennies since 1983 are made almost entirely of zinc, covered with a thin coating of copper. Therefore, what you have is either a zinc penny that did not get its copper coating (worth abuot a dollar), or a normal penny that has been silver plated (no added value). You should be able to determine this by weight. A normal penny will weigh 2.5 grams. So if yours weighs less, then it's missing its copper coating. If it weighs more, then it's been silver plated.
