The cost of minting them. Today's pennies are zinc (cheap) coated with a copper wash, and still cost more to make than they are worth.
The U.S. still mints pennies, but Canada discontinued them in 2012.
In 1982 the mint struck pennies from solid bronze and from copper-plated zinc. Bronze cents weigh 3.1 grams and the zinc once weigh 2.5 grams. Bronze pennies were discontinued in mid-1982
Bronze.
All wheat pennies are bronze, so please be more specific and post new question.
No, modern pennies in the United States are not made of bronze. Since 1982, they have been primarily made of zinc with a thin copper plating. Prior to that, from 1909 to 1982, pennies were made of 95% copper and 5% zinc, which is often referred to as bronze, but the current composition is different.
1860 The last copper pennies were made in England, and the same year the first bronze pennies were made.
Great Britain discontinued the 1/2p coin in 1984 The U.S. discontinued its 1/2¢ coin in 1857
All British predecimal Pennies, Halfpennies and Farthings minted since 1860 are bronze.
Even though production was discontinued, there hasn't been a corresponding spike in value. There are still millions and millions of Canadian pennies in existence.
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.
All British general circulation predecimal Pennies, Halfpennies and Farthings were made from bronze from 1860 to 1967.
All 1941 pennies are made of bronze which is mostly copper.
