All coins are made of some type of metal, but not all coins are made of copper.
Silver U.S. coins are made entirely of silver and copper -- neither of which is a magnetic metal. Base metal coins that are magnetic, likely contain some amount of iron -- a magnetic metal, or a high concentration of nickel which is also attracted to a magnet.
Most coins nowadays are not made of iron. Most coins in the United States are made of Nickel and Copper (small amounts of Copper in pennies).
Yes... Especially pennies because of the copper in them. Most coins are made of metal: nickel, copper, iron or steel. Some rare and expensive ones are made of nearly pure gold and silver. All the metals are good electricity conductors.
The above answer is NOT correct. Coins are not magnetic, but depending on the metal they're made of SOME of them may be attracted to a magnet. Specifically, coins made of steel or high concentrations of nickel will be attracted to a magnet but those containing other metals such as copper or aluminum are not. Some Canadian, British, and European coins are made of steel as were 1943-dated US cents; all of these are attracted to a magnet. Other coins though have a lot of copper in them (e.g. most US coins except cents) and these are NOT attracted to a magnet.
U.S. one cent coins were 95% copper until 1982. 1982 was the transition year from copper to zinc, so there are copper coins dated 1982 and zinc coins dated 1982. From 1983 to 2012 the coins are 99.2% zinc & .008% copper with a copper plating.

Copper coins are made of metal, as copper is a metal. However, most coins are not pure copper. In the US, the modern penny (one cent) is copper-coated zinc. There is copper in dimes, quarters and half-dollars as the inner "sandwich" of clad coins, between layers of zinc. There is also copper in the Presidential $1 coins, because the coins are made of brass (88.5% copper, with zinc, manganese, and nickel), the same alloy used in the earlier Sacajawea $1 coin.
Authentic coins were made of copper. Many replicas and fake coins made from "base metal" exist.
a coins texture is different because it is much harder and mostly made out of copper and metal.
Copper-plated steel has been used since 1993.
The metal composition of penny coins made after 1982 is 97.5 percent zinc and 2.5 percent copper. The first penny coins, from 1793 to 1837, were made from pure copper.
2p coins were made of bronze from their introduction until 1992, when the rising price of copper forced the Royal Mint to start making the coins from steel with a thin copper plating.
Copper
At the present time, the US has silver colored coins made out of nickel, alloys of copper and nickel, and other metals, but it no longer uses actual silver, which is very expensive. Historically, when coins were first introduced in earlier civilizations, and even in the earlier years of US history, the value of a coin was the value of the metal of which it was made. Silver coins were valuable because they were made of silver, a precious metal, gold coins were even more valuable, and copper coins were less valuable because copper is a less expensive metal, although still expensive enough that coins made out of copper have value because of their metal content. Now the value of US coins is like the value of US paper currency, something that the government declares, rather than being the result of valuable metal content. But out of tradition, the higher denominations are still silver at least in color, and pennies are still copper.
Copper was a relatively cheap metal to make low denomination coins from, but due to inflation and the rising price of copper, it became less economical to continue making one and two cent coins.
U.S. coins used to be made with silver, typically a blend of 90% silver with 10% copper. Then modern dimes, quarters, and half dollars are nickel-coated copper. Nickels are made with 25% nickel and 75% copper. There aren't any coins made of a silver/nickel blend.
US Coins from 1965 to date are made of copper, nickel, zinc and manganese, depending on the denomination.
