Since 1982 US cents have been made of copper-plated zinc.
The Mint buys large rolls of zinc stock from metal suppliers. The stock is approximately the thickness of a finished cent, with slight differences to allow for changes during the striking process. The process starts a bit like baking cookies: the stock is unrolled (think of a giant roll of dough) and fed into a press that punches out circular blanks, similar to the way a cutter would press out blanks for making cookies.
The blanks go through a process to clean them of debris and oils. Next they're fed into a machine that squeezes the edges slightly to produce the raised rim seen on all US Coins. After that, the blanks are fed into hoppers that feed high-speed presses that strike the front and back images on each one.
Finally the zinc coins are put into a chemical bath that deposits a layer of copper on the outside, both so that the coins look like their bronze predecessors and so that the underlying zinc won't corrode.
Pennies are made up of 97% zinc, and 3% copper. All though this seems unbelievable, it is true. Earlier in History, pennies were made up of jut copper, but that got too expensive, so the U.S government changed the pennies material, to Zinc, and copper.
An alloy of 95% copper, 5% zinc. The change to copper-plated zinc took place in mid 1982.
Pennies are zinc, but they are copper plated.
Originally pennies were made of copper. They are now made mainly of zinc.
A penny is made put of copper
No. Pennies were made of copper (Now US pennies are made of copper plated zinc) Magnets are made of iron or other ferro-magnetic metals.

It depends on which country we are talking about. For the US, there is only one magnetic coin the 1943 steel penny. For Canada, there have been some magnetic pennies made since 2000, though there were zinc pennies made until 2008. For the UK, pennies have been magnetic (copper plated steel) since 1992.
quarters are made of steel, and pennies are made of copper. Copper doesn't conduct electricity
pennies are made of mostly zinc but have some copper in themMoreThe composition of US cents was changed from bronze in mid-1982. The coins now have a zinc core plated with copper (rather than mixed together). Zinc makes up 97.5% of the coin by weight.
The US never made silver pennies. In 1943 the US made steel pennies. These are often mistaken for silver pennies.
Copper
According to the US mint, 6015.2 million pennies were made in 2012.

Nobody. The US never made silver pennies. In 1943 the US made steel pennies. These are often mistaken for silver. In 1943 Abraham Lincoln was on the US penny.
3.11 grams for pennies made from 1959 to 1982
Copper zinc
Yes
No. Pennies were made of copper (Now US pennies are made of copper plated zinc) Magnets are made of iron or other ferro-magnetic metals.
No, but in 1943 US pennies were made from steel coated zinc. These have become a collector favorite.
On US cents from 1793 to 1958 .
The US has never made silver pennies. It would cost way to much to make silver pennies because of the value of silver. Many people think that in 1943 pennies were made out of silver however they are actually made out of zinc and steel.
