1982
The last year for copper US pennies was 1982.
The last year for 100% pure copper cents was 1857.
The switch was made in 1982. Some pennies that year are copper, and others are zinc. If you can't tell the difference, then use 1981 for the last year.

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.
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.
1982 was the last year for 95%-copper pennies. And the first year for the zinc pennies. They made both types that year, and the only way to tell them apart is by weight -- the zinc pennies are lighter.Answer100% copper pennies were last minted by the US in 1857. These were large cents, about the size of the "golden" dollar coins. The Flying Eagle and Indian Cents from 1856 to 1864 were 88% copper and 12% nickel. Beginning in 1864 Indian Cents, and later Lincoln Cents, were minted in 95% copper and 5% tin, technically this is bronze. AnswerAnother way to tell the copper penny from the copper coated zinc penny is when a penny is dropped on a hard surface the copper penny will have a ringing sound, the zinc penny will not ring.
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.
