The Royal Mint does not reveal how much it costs to produce coins.
Rest assured, however, that if the cost of production comes anywhere near the face value of the coin, the coin will either be discontinued or made from cheaper materials in future.
Pennies before 1982 were made of 95% copper, which has a higher density compared to the 97.5% zinc composition used in pennies starting in 1982. This change was made due to the increasing cost of copper.
Food was definitely less expensive in the UK in 1982 than it is in 2014. A loaf of bread was about 32 pennies while a pint of beer was about 73 pennies. A pint of milk was about 20 pennies at this time.
The price of the copper to make the coin cost more than 1 cent.
What country are you talking about? New U.S. cents are not magnetic; they're made of copper-plated zinc. The only magnetic U.S. cents were the steel ones minted during 1943 so copper could be used in ammunition. New Canadian cents and British pennies are magnetic because they're made of copper-plated steel. The price of copper went up so much that it cost more than a penny to mint the coins, so the governments were losing money on each one. They switched to steel as a cheaper alternative.
Copper is used for pennies because it is a cost-effective material and has good durability. It is also easily distinguishable from other coins. However, due to its high cost of production, the composition of U.S. pennies was changed in 1982 to include primarily zinc with a thin copper coating.
Pennies made before 1982 were composed of 95% copper and 5% zinc, while those made in 1982 were transitioned to a composition of 97.5% zinc and 2.5% copper. This change was primarily due to the rising cost of copper which made it more expensive to produce the coin.
Pennies in the United States are currently made of a copper-plated zinc composition, consisting of 97.5% zinc and 2.5% copper. This composition has been in use since 1982 as a more cost-effective alternative to the previous solid copper pennies.
An increase in the price of copper makes producing pennies more expensive. The mint may change the composition of pennies to a cheaper material to reduce production costs and maintain profitability. By using a different material, such as zinc, the mint can continue to meet demand for pennies without being significantly impacted by the rise in copper prices.
Pennies are made of zinc with a thin copper plating to reduce cost. This change was made in 1982 to save money, as zinc is cheaper than the bronze used previously. The copper plating gives pennies their traditional color and appearance.
The US never made silver pennies. It would cost too much for the mint to make them. Your coin is plated silver this adds no value to the coin.
The copper in a US cent made before 1982 is worth almost 2 cents. Those made after 1982 are worth much less than 1 cent (but the cost of producing them is about 1.5 cents). Both types were made in 1982. But before you start sorting your pre- and post 1982 pennies, you should know that there is an administrative order prohibiting the "melting or exporting of large numbers of one and 5 cent coins" which could result in a fairly large fine.
