Well, there are two ways. You could scratch it or melt it over a flame to check composition. Or, you could check the date.
The first US penny was minted in 1793 and was 100% pure copper. In 1856 the cent's size was reduced and they were changed to an alloy that was 88% copper and 12% nickel, although pure copper large cents continued to be produced as well for one more year. The nickel alloy was hard to strike and the coins had a whitish appearance so in 1864 a bronze alloy of 95% copper and 5% tin and/or zinc was adopted.
In 1943 the US made the famous steel pennies. These were made for only one year and were zinc coated steel. There was a copper shortage because of the war. There were a few copper pennies made that year also and they are now quite valuable.
Bronze pennies were resumed in 1944. In 1962 the US stopped using tin pennies and they became just 95% copper and 5% zinc.
In the middle of 1982 the price of copper rose to the point where each penny contained more than 1¢ worth of metal. The composition was changed again to copper-plated zinc (97.5% zinc and 2.5% copper.) So, unless you have a US large cent it is in some way less than 100% pure copper.

Boiled Down If it's dated 1982 or older, then it's copper ... If it's dated 1983 or newer, then it's zinc with a thin copper plate ... If it's 1982, weigh it -- if it's 3.1 grams then it's copper .. if it's 2.5 grams then it's zinc. Unless it is one of the few mistakes the U.S. made in 1983 when they made about 100 copper pennies that are very rare and expensive today.
zinc pennys are silver....
Pence is the plural of Penny. One Penny, Two Pence.
Pennies are made of zinc coated with copper.
Yes, as long as there is no chemical interaction between them.
If you refer to the GEORGE III 1797 "Cartwheel" Penny and Twopence, they are both made from copper and are of almost identical appearance, the Penny is a little over 30 mm in diameter and the Twopence is much larger at about 40 mm in diameter.
What is the difference between the 1911 Penny minted in Perth? (and what?)No Australian Pennies were minted at the Perth Mint until 1940.
The copper content of a penny was changed because the old copper substance made people have skin irritations and rashes. The new penny does not do that.
You can tell if a penny is made out of zinc or copper by the date on the penny. If the date is before 1982 then the penny is 95% copper. Pennies dated 1983 or later are 97.5% zinc with a thin copper coating.
zinc is 97.5% of the penny and copper is 2.5% of the penny
did they make 1982 copper penny by mistake
Copper is a conductor, so and pennies are coated in copper.
Copper reacts with the oxidilized copper on the penny.
A Shilling was a coin made of silver, or in later years, copper-nickel, and of silvery appearance, approximately 23.5 mm in diameter. A Penny was a copper or bronze coin approximately 30.8 mm in diameter. There were 12 Pence to a Shilling. These coins are now redundant in all of the Commonwealth countries that were using them.
All Lincoln cents minted between 1909 and 1981 (except for 1943) have the same copper content: 95% copper with 5% zinc. The metal ratio was changed in 1982.
US Coins the last year for a copper (actually bronze) penny is 1982. In 1982 the penny was made as a copper coin and a copper plated zinc coin. You have to weigh them to tell the difference. Bronze cents weigh 3.11 gm and zinc ones weigh 2.5 gm. The penny has remained a copper plated zinc since 1982 however there is talk of changing it again to a copper plated steel coin. In 1943 the Lincoln US cent was steel coated with zinc because the copper was needed for ammunition during the War. In 1944 it went back the copper coin. Today the cost of copper is too high to make a solid copper coin/penny. In fact the cost of stamping/minting the coins and raw materials, the penny and nickel cost more to produce than their face value.
A genuine 1943 copper cent is worth tens of thousands of dollars, but a lot of what's out there are fakes. An easy way to tell the difference between a real and fake is that the real thing is NOT magnetic. Pennies that year were made of steel, and the fake copper ones are usually copper-plated steel cents.
No, copper and zinc are not magnetic.
The penny is made out of copper.
You have a penny in both types of pools ... ???
