Pennies today are made of zinc blanks (circles of zinc are punched out of sheets of zinc, like cookies are cut out of a sheet of dough with a cookie cutter). The zinc blanks are then electroplated with copper in plating barrels (we have an article with pictures on line about barrel plating), so the core of the penny is zinc but the skin is copper.
After the copper plating, they are stamped with the familiar head of Lincoln and the date, etc. Coins such as pennies have a raised rim (the lip around the penny is thicker than the body of the penny); this is created by rolling the coin through a passage that is slightly smaller than the original size of the blank. The higher edge helps protects the design from excess wear.
No not anymore starting in 1982 Lincoln cents are made of 97.5% ZINC and 2.5% 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.
pennies these days are not completely made of copper they are just dipped in copper giving them that finished look
No. In Canada, they are 99.9% copper and 0.1% silver. I am not sure what it is in the USA so go to the mint.
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.

up to 1982
There are no exact records of the number of copper pennies made in 1943. It was about 40. Most pennies that year were made of steel.
It depends on what year they were minted but from 1982 to date Lincoln cents are made from .975% zinc & .025% copper.
pennys
modern pennys are only copper coated
And lots of other things. There are pipes in cars made with copper and quarters and dimes have copper inside of them. There are lots of other uses as well.
All US pennies made before 1982 are copper, along with some made in 1982 that are copper, however, copper-coated zinc pennies were also used during that year making identification by weighing necessary.
Zinc covered in Copper
The switch was made in 1982. Some pennies that year are copper, and others are zinc. If you can't tell the difference, then use 1981 for the last year.
pennys are 97.5% zinc and 2.5% copper
The answer depends on how many pennies are in each box.
