The Zinc-Coated Penny Dilemma

I have a zinc-coated penny dated 1943. I found it one day while out for a walk. I understand that these pennies were minted during the time of WWII (hence the date) and that this was done to preserve copper for the war efforts. I am still confused as to what all the surplus copper was used for and when the circulation of these zinc-coated pennies was discontinued. I have been fascinated with this "unusual" penny ever since I found it. Any information would be helpful. Thank you.

Take a magnet and hold it up to that '43 penny. You'll soon learn it isn't zinc coated, but rather stamped from steel. Copper was rationed for a variety of reasons, I'll bet the biggest was for the manufacture of bullets.

I was wondering why pennies aren't made entirely out of zinc? Why do they place a copper coating over the zinc.

Hi Alyson. Zinc corrodes too rapidly to be useful as a coin.
