Get it to rust: Green rust: copper, red rust: iron, no rust: silver.
Not exactlyUS cents don't rust (except for 1943 ones). "Copper" pennies are made of bronze which oxidizes to the familiar dark brown color. And US cents have NEVER been made from iron or silver. Plus letting a coin oxidize is a sure way to destroy any collector value it may have.The best way to tell is by the penny's date and/or weight.
- Cents up to 1857 were pure copper
- Cents from 1858 to mid-1864 were made of copper-nickel
- Cents from mid-1864 to mid-1982 (except for 1943) were made of bronze.
- Cents made in 1943 were struck in zinc-plated steel due to wartime shortages.
- Cents made since mid-1982 are zinc with a thin copper coating.

What year were full copper pennies no longer made?
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.
