The weight for the Steel cents are 2.7 grams. So it is an altered copper cent at 3.1 grams with extra plating of nickel and chrome, adding attraction. The difference? The steel cent leap towards a magnet. This on is just showing an attraction. Don't believe me try the same test on a 1943 steel cent. See how close you need to be to see it jump to the magnet. Then try to see how close the magnet needs to be on your altered coin. (literally touching it before it is attracted slightly)
