Steel cents were only made in 1943 and are easily detected because they stick to a magnet. Your coin is almost certainly a zinc cent that's missing its outer copper plating; it shouldn't stick to a magnet.
There can be several reasons a zinc cent is missing its plating, but the only type that's valuable is a coin that accidentally didn't go through the plating process at the Mint. You'll need to have the penny evaluated in person by an expert to be sure.
