1981 was both the last full year that 95%-copper cents were minted and the highest-mintage year for that metal composition. Almost 13 billion were struck.
More cents have been struck in other years (1994, for instance) but those coins aren't copper, only copper-plated zinc.
There are no exact records of the number of copper pennies made in 1943. It was about 40. Most pennies that year were made of steel.

All of them were supposed to be made of steel, however there were a few copper coins accidentally struck that year. Its extremely rare to come across copper pennies from that year.
American pennies have been copper in every year except 1943, when copper was scarce and pennies were made of steel. These days, pennies are more zinc than copper.

1860 The last copper pennies were made in England, and the same year the first bronze pennies were made.
Pennies are made of zinc and other alloys with a copper coating, pennies made before 1964(or around this year) they were made of just copper. What you see on a penny is not rust but corrosion of the copper coating.

The materials used to mint pennies has changed. Originally, pennies were made of almost pure copper. Today, British pennies are made of nickel/steel blanks coated in copper, and US "pennies" (actually cents) are made of zinc blanks coated in copper.
All US pennies made before 1982 are copper, along with some made in 1982 that are copper, however, copper-coated zinc pennies were also used during that year making identification by weighing necessary.
The last year for 100% pure copper cents was 1857.
Starting mid-year in 1982, pennies were made with a zinc core and copper plating. This would give them a 97.5% zinc content and 2.5% copper content.
It depends on what year they were minted but from 1982 to date Lincoln cents are made from .975% zinc & .025% copper.
