Have you ever wondered why are pennies made of copper? This question has a fascinating history behind it that spans over two centuries. In this comprehensive guide, we’ll walk through the origins of the penny, the metal composition over time, and the reasons copper emerged as the dominant metal used in penny production today.
If you don’t have time to read the full history, here’s a quick answer: pennies are made of copper because it is a durable, abundant, and inexpensive metal that allows the United States Mint to mass produce billions of pennies each year at minimal cost.
A Brief History of the Penny in America
Introduction of the Penny in 1787
The penny has been a staple of American currency since its introduction in 1787. It was first authorized by the Coinage Act of 1792, which established the United States Mint. At this time, the penny was made of pure copper and had a diameter of 19 millimeters.
The design featured a bust of Lady Liberty on the obverse and an eagle on the reverse.
Penny Composition Shifts to Bronze in 1864
In 1864, due to rising costs of copper during the Civil War, the composition of the penny was changed. The new penny was made of 95% copper and 5% tin and zinc, resulting in a stronger and more durable coin.
This new composition, known as bronze, allowed for the production of more pennies at a lower cost. The design of the penny remained relatively unchanged during this transition.
Zinc Coating First Used in 1962
In 1962, the penny underwent another significant change. To combat issues of corrosion and tarnishing, the United States Mint began coating pennies with a thin layer of zinc. This coating, known as the “zinc cent,” helped to preserve the appearance of the penny and extend its lifespan.
The composition of the penny remained the same, with 95% copper and 5% zinc, but the outer layer was now zinc rather than copper.
Throughout its history, the penny has played a crucial role in American commerce. Despite debates surrounding its value and usefulness, the penny continues to be minted and used in everyday transactions.

Why Copper is Ideal for Penny Production
Copper is Durable and Wears Well
One of the main reasons why pennies are made of copper is because of its durability. Copper is a highly resilient metal that can withstand the test of time, making it perfect for coin production. Unlike other metals that may corrode or tarnish easily, copper maintains its integrity and does not deteriorate quickly.
This means that pennies made of copper can last for many years without losing their value or becoming damaged. Some copper pennies from as far back as the early 1900s are still in circulation today!
Copper is Abundant and Inexpensive
Another advantage of using copper for penny production is its abundance and affordability. Copper is one of the most abundant metals on Earth, making it readily available for coin minting. Additionally, compared to other metals like silver or gold, copper is relatively inexpensive, which helps keep the cost of producing pennies low.
This is particularly important considering the large quantity of pennies that are minted each year. So, using copper not only ensures a steady supply of material but also helps keep the overall cost of producing pennies affordable.
Malleability Allows Efficient Penny Production
The malleability of copper is another factor that makes it ideal for penny production. Copper is highly malleable, meaning it can be easily shaped and molded into the desired coin shape. This property allows for efficient coin production, as the metal can be easily pressed and stamped into pennies without much difficulty.
This makes the manufacturing process faster and more cost-effective. The malleability of copper also allows for intricate designs and engravings to be added to the pennies, enhancing their aesthetic appeal.
Alternative Penny Compositions Considered
Throughout history, the composition of pennies has undergone several changes, with alternative materials being considered at various points. These alternatives were explored due to factors such as cost, availability of materials, and durability.
Let’s take a closer look at some of the alternative compositions that were considered for pennies.
Steel Pennies in 1943
In 1943, during World War II, a shortage of copper led to the temporary use of steel for penny production. Copper was a crucial material for the war effort, so the United States Mint decided to mint pennies using zinc-coated steel.
These steel pennies, also known as “wartime pennies,” were produced for only one year and are now highly sought after by collectors.
Aluminum and Steel Debate in the 1970s
In the 1970s, there was a debate about whether to change the penny’s composition to aluminum. Proponents of this change argued that aluminum pennies would be lighter, cheaper to produce, and more resistant to corrosion.
However, opponents raised concerns about the potential confusion with dimes, which are also made of silver-colored metal. Ultimately, the proposal to switch to aluminum pennies was rejected, and copper continued to be the main component of pennies.
Zinc and Steel Tests in the 1980s
In the 1980s, the United States Mint conducted tests using zinc-coated steel for penny composition. The goal was to evaluate the feasibility of using a more cost-effective material without compromising the coin’s quality.
These tests aimed to address concerns such as the durability of the steel coating and the potential for zinc to react with other metals in circulation. Ultimately, the tests did not lead to any changes in the penny’s composition, and copper remained the primary material used.
It’s worth noting that the composition of pennies can vary in different countries. For example, the penny in Canada is primarily made of copper-plated zinc. Each country evaluates different factors when considering alternative compositions, including cost, availability of materials, and public opinion.

Impact of Rising Copper Prices
The rising prices of copper have had a significant impact on the production and value of pennies. Since the mid-20th century, the value of the penny has been decreasing due to the increasing cost of copper. Before 1982, pennies were made of 95% copper, which made them more valuable.
However, as copper prices started to rise, it became more expensive to produce pennies with such a high copper content.
Decreasing Penny Value Since Mid-20th Century
As copper prices continued to rise, the United States Mint decided in 1982 to change the composition of the penny. The new pennies were made of 97.5% zinc and 2.5% copper, which significantly reduced the cost of production.
This change resulted in a decrease in the intrinsic value of the penny, as the copper content became less valuable.
Since then, the value of the penny has continued to decline. In fact, according to a study conducted in 2019, the production cost of a penny was approximately 2.1 cents. This means that it costs more to produce a penny than its actual value, resulting in a loss for the government.
Proposals to Change Composition or Retire Penny
Due to the decreasing value and rising production costs, there have been proposals to change the composition of the penny or even retire it altogether. Some argue that switching to a less expensive metal, such as steel or aluminum, could help reduce production costs.
Others believe that it is time to phase out the penny, as it has become more of a burden than a useful form of currency.
However, there are also arguments for keeping the penny in circulation. Proponents of the penny argue that it is an important part of American history and culture. They believe that removing the penny would disrupt the traditional pricing system and potentially lead to rounding issues.
It is important to note that any decision regarding the future of the penny would require careful consideration and analysis of the potential economic and social impacts. The United States Mint continues to monitor the situation and evaluate the best course of action.
Why Are Pennies Made Of Copper – Conclusion
In conclusion, the penny has been made primarily of copper for most of its existence due to the metal’s durability, abundance, and cost-effectiveness. Despite periodic spikes in copper prices and debates around using cheaper alternatives, the desirability and efficiency of copper have kept it as the standard metal used in penny production over the last 200 years.
While the future composition of the penny is unclear, its copper content reflects both historical tradition and practical considerations that have stood the test of time.
