The last copper (actually bronze) cents were made in mid-1982. The mints gradually changed over to copper-plated zinc as the remaining stocks of bronze blanks were used up.
copper cent and half-cent pieces
The "S" mint mark is used by the San Francisco mint and is located just below the date on the 1941 Lincoln cent.
The price of copper increased during the early 1980s, and by 1982 it cost the Mint more than 1 cent to mint each cent. Trial strikes in different metals were made but a combination of price and lobbying by zinc producers convinced the Mint to switch from solid bronze to copper-coated zinc. The change was made in the middle of 1982, so coins with that date may be made of either composition.
Without knowing details like the date, mint mark, and condition, the best possible answer is one cent.
It is called a Lincoln Cent and it is valued from $1 to $75,000 depending upon the mint mark, the condition of the coin and any mint errors.
From 1793 to date the mint has NEVER used a "P" mintmark on any one cent coin.
Between changing the composition of the US one-cent coin (often referred to as a "penny," even though the word has never appeared on the US coin) and experimenting with the size of the date, there are 7 different types of 1982 pennies: * 1982 copper, small date * 1982-D copper, small date * 1982 copper, large date * 1982-D copper, large date * 1982 copper-plated zinc * 1982-D copper-plated zinc * 1982-S copper proof It's easy to tell between the different mint marks; just look below the date. The plated zinc cents are slightly lighter, and don't give the distinctive "ring" of a copper (actually a copper-zinc alloy) cent. The only way to tell between the date sizes is to study pictures of the two, and notice the distinctions in how they look. Note that there was only one proof type, minted only in San Francisco.
If you're referring to a U.S. cent, they were all made of bronze from mid-1864 to 1942 and again from 1944 to the middle of 1982(*). That means there are hundreds of possible coins to choose from so more information is needed - the date, and if the coin is dated 1908 or later, whether it has a mint mark. To find the mint mark on a 1908 or 1909 Indian cent, look on the back under the wreath to see if it has a small "S". On Lincoln cents, look under the date for a D or S. Any cent that doesn't have a mint mark is normal, it was simply made in Philadelphia. (*) To fill in the gaps, cents were made of steel in 1943 to save copper for the war effort, and the composition was changed to copper-plated zinc in 1982 because copper had become too expensive.

The first true copper penny issued by the US mint was minted in 1793, commonly called a "large cent" due to it's size. The first predominantly copper "small cent" was issued in 1864, after the 1856-1863 cents were a 88-12 copper-nickel alloy that gave them a nickel-like appearance. In 1982, the US mint began using a copper coated zinc alloy for pennies, ending the run of the solid copper penny.
The mint mark on the Lincoln cent is under the date on the obverse of the coin, it can only be a "D" or "S" no other mint marks are used.
In 1946 the US Jefferson Nickel contained 75% copper and 25% mickel.
