Modern British pennies are now made of copper-plated steel. For example, in India some coins have been made from a stainless steel that contains 82% iron, 18% chromium, and many other countries that have minted coins that contain metals now worth nearly the coin face-value, are experimenting with various steel alloys.

Are pennies iron?
No American coin contains any iron. Cents are made of zinc with a small amount of copper; nickels, dimes, quarters and halves are made of a nickel/copper blend; and our dollar coins contain copper, zinc, nickel and manganese. The cent was made of steel in 1943, to conserve copper during war time.
What kind of metal are US coins made out of?
US coins are made up of copper and nickel. Nickel is magnetic so US coins should be magnetic, but when checked, they came up to be non-magnetic.
Why did they use iron as a coin?
The region didn’t have a large copper reserve and the Song emperor looted most of the gold, copper coins after taking down the original kingdom. However, iron was relatively cheap. Sometimes one copper coin could be used to exchange for ten iron coins thus making it inconvenient to buy things using iron.
Why are coins and pennies made of steel?
We have studied that the coins and pennies made of steel are magnetic because steel is made up of iron. Iron is that metal that shows ferromagnetism due to unpaired electrons. Unpaired electrons create their magnetic field under the applied magnetic field and attract to them.
