How much is a 1943 steel penny worth if it sticks to a magnet?

Could you please clarify the value of a 1943 steel penny that is magnetic? It's intriguing to know how much such a unique coin, often mistaken for being made of copper due to its appearance, might be worth when it possesses this unusual property. Does its magnetic nature significantly alter its market value, or is it merely a curious feature that collectors might find interesting but does not necessarily translate into a higher price tag?
