What metal is a penny made of?
That depends on which year. If it's 1983 or later, it's copper-plated zinc (97.5% zinc and 2.5% copper). 1981 and earlier is 95% copper mixed with 5% zinc (the switch happened in 1982, so both types exist for that date). In 1943, copper was needed for the war effort, so all pennies that year were solid steel coated in zinc. The above answer is partially correct.

Substance of a penny?
Assuming you're asking what a US cent is made of: Since mid-1982 all US cents have been made of 97.5% zinc with 2.5% copper plating. From mid-1864 to 1942 and from 1944 to mid-1982 they were bronze, 95% copper and 5% tin and/or zinc In 1943 they were made of zinc-plated steel due to wartime copper shortages. From 1857 to mid-1864 they were made of copper alloyed with nickel. Before that they were pure copper.
German silver is an alloy of what?
Silver is a fairly soft metal, and to make it more durable for (say) cutlery use, copper is alloyed with it to harden it. With 7.5% of copper, this is Sterling Silver.Silver also finds wide application in solders and brazes for joining metals, and many admixtures are used.
Are all pennies copper?
They all contain some copper, but the amount depends on when it was made. Those minted before 1982 were 95% copper with 5% zinc, while those minted since then are 97.5% zinc with only 2.5% copper.
What is the composition of a 1984 penny?
In 1982, the composition of pennies was changed from almost all copper, to almost all zinc, with a thin outer layer of copper. If the coin blank does not get its outer copper layer, the zinc will remain exposed, and it will look just like one of the 1943 steel cents -- which are actually coated with zinc.

Are all pennies made of copper?
Most modern pennies or cents have almost no copper in them, no matter what country issues them. The reason is that copper now sells for about $4/lb so a 1-cent copper coin would contain much more than one cent's worth of metal. Today, US cents are made of zinc plated with copper; Canadian cents and British pennies are made of steel plated with copper. US "copper" cents were actually bronze, which is an alloy of copper with tin and/or zinc added. Bronze cents were discontinued in mid-1982 when the price of copper rose steeply.
