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.
The density of copper is 8.94 g/cm3. This can be calculated by dividing the total mass of the pennies (36.93 g) by the total volume they displace (4.13 cm3). This gives the density of copper as 8.94 g/cm3.
No, wheat pennies were primarily made of copper during 1909-1942 and in 1944-1958. In 1943, due to copper shortages during World War II, steel pennies were minted which are distinctly different in appearance.
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.
38000 copper pennies would weigh approximately 94.7 kilograms or 209 pounds.

1860 The last copper pennies were made in England, and the same year the first bronze pennies were made.
Pennies from 1982 and before were all copper
No.
All most none only .008% Copper & .992% Zinc
Well depending if your talking about all the different country's pennies, then Im not sure. But I do know that the pennies made in Canada and the states are. The main metal in these pennies are copper, and copper is worth more then what the penny is worth, so sometime in the near future they will atop making pennies.
Currently yes.
No, pennies do not contain gold. Modern pennies are mostly zinc with a little copper, older pennies are mostly copper with a little zinc.
All 1941 pennies are made of bronze which is mostly copper.
copper is important because it makes pennies and pennies are good
1857, unless you're referring to Lincoln pennies, which were only 95% copper until 1982 when they were changed to zinc.
240 copper pennies equal a pound.
No. Pennies made before 1982 were 95% copper, with 5% zinc.
