Copper shortage in world war 2
The story isn't exactly as you heard it. In 1943 there was a copper shortage due to its use in ammunition during WW2. But pennies were still needed, so the Mint switched to using zinc-plated steel. Over a billion of these coins were minted, but they proved unsatisfactory (they looked too much like dimes and had a nasty habit of rusting!) so copper cents were resumed in 1944.

Food shortage is when there is not enough food. When the amount you have does not equal or exceed the amount that you need, you have a shortage. In this case, the shortage is of food.
The 1943 US penny reflects the shortage of some metals due to production for the war. Instead of copper, the pennies were made of steel, and are grey in color.
I would estimate that a 1943 D copper cent would bring somewhere between $40,000 and $100,000, depending on its condition and the abilities of the selling auction house. Owing to a shortage of copper during WWII (especially the year of 1943), the Treasury Department resorted to the use of zinc-coated steel for cents. No bronze (copper) cents were INTENDED to be minted in 1943, but at least 12 and as many as 40 copper planchets were struck with the 1943 dies.
The grammar of the sentence "there are no shortage of options" is incorrect. It should be "there is no shortage of options" to ensure subject-verb agreement and correct use of the term "shortage."
No one-cent coins were minted in 1815 due to a copper shortage caused by the War of 1812 with Great Britain. Copper was placed on the "banned list" after the war. The Mint had been importing cent planchets from Great Britain because at the time, we did not have the ability to produce them.
