The US never made any iron cents. All US cents dated 1976 were struck in bronze. And in any case iron isn't suitable for coins because it rusts and can be brittle.
An iron coin would stick to a magnet, so that should be the first test if you suspect a coin is made of that metal, steel, or pure nickel (note - US nickels are mostly copper!)
The only US Coins ever made of a magnetic metal were the famous wartime steel pennies dated 1943.

The 1944 steel penny is valued highly because it was produced using leftover steel from World War II, as the U.S. Mint switched back to copper for the penny in that year. In contrast, the 1943 steel penny, made from zinc-coated steel to conserve copper during the war, is much more common, making it less valuable. The rarity and historical significance of the 1944 steel penny contribute to its higher market price, while the 1943 version is abundant and widely circulated.
