The Evolution of the Penny
The penny, the iconic symbol of American currency, has a fascinating history and has evolved over the years. From its humble beginnings to its current design, the penny has undergone several changes in composition and design that reflect the changing times.
In the early days, pennies were made of pure copper and featured various designs. The “Flowing Hair” and “Liberty Cap” designs were some of the notable designs during this period. These early pennies were a representation of the growing nation and its values.
However, in 1857, the composition of the penny changed. It became 88% copper and 12% nickel, creating a more durable coin. This change in composition allowed the penny to withstand wear and tear better, ensuring its longevity in circulation.
In 1909, the penny took on a historic significance. Abraham Lincoln became the first president to be featured on the penny, honoring his contributions to the United States. This design, known as the Lincoln penny, still remains in circulation today.
In an effort to reduce production costs, the composition of the penny changed once again in 1983. It shifted to a copper-plated zinc composition, retaining its familiar appearance while utilizing less expensive materials. This change demonstrated the practicality and adaptability of the penny throughout its evolution.

The Design of the Penny
The design of the U.S. penny has evolved over the years to commemorate important events and milestones in the life of President Abraham Lincoln. The current design, known as the “Union Shield” design, features a profile of Lincoln on the obverse side of the penny.
On the reverse side, you will find a shield with 13 vertical stripes, symbolizing the original colonies, and the national motto inscribed in a horizontal bar above. This design represents the unity and strength of the United States.
Prior to the Union Shield design, the reverse side of the penny featured the Lincoln Memorial, a famous monument dedicated to President Lincoln.
The U.S. penny, often referred to as the Lincoln penny or Lincoln Memorial penny, serves as a tribute to one of the most influential presidents in U.S. history.
Characteristics of the Penny
When it comes to the penny, there are several important characteristics to note. From its dimensions to its composition, each element contributes to the overall design and functionality of this iconic coin.
Penny Dimensions
The penny has a diameter of 0.750 inches (19.05 mm) and a thickness of 0.0598 inches (1.52 mm). These dimensions have remained consistent throughout the history of the penny, regardless of its composition.
Penny Composition
The current composition of the penny is copper-plated zinc, with 97.5% zinc and 2.5% copper. This change in composition was implemented in 1983 to reduce production costs, as the price of copper continued to rise. The copper plating gives the penny its distinct color and appearance.
The obverse of the penny features the word “LIBERTY” and the national motto “IN GOD WE TRUST.” These inscriptions serve as a representation of the values and beliefs of the United States. On the reverse, you’ll find the words “UNITED STATES OF AMERICA,” “E PLURIBUS UNUM,” and “ONE CENT.” These inscriptions highlight the coin’s value and identity.

History of Penny Composition
The composition of the penny has changed over the years, driven by factors such as the availability and cost of materials. Let’s take a look at the different compositions the penny has had throughout its history:
1. Pure Copper Pennies (Prior to 1857)
Before 1857, pennies were made of 100% copper. These pennies had a distinct reddish-brown color and weighed approximately 10.89 grams each. Here’s an image of a copper penny from this era:
2. Copper-Nickel Blend (1857-1864)
From 1857 to 1864, the composition of the penny changed to 88% copper and 12% nickel. This change was made to address the rising cost of copper. The weight of each penny remained the same, around 10.89 grams.
3. Zinc-Coated Steel Pennies (1943)
During World War II in 1943, pennies were temporarily made of zinc-coated steel. This was done to conserve copper for war efforts. However, due to issues with the appearance of the coins and confusion with dimes, this composition was only used for one year. Steel pennies weighed approximately 2.7 grams.
4. Copper-Plated Zinc Pennies (1982 – Present)
In 1982, the composition of the penny changed to what we still use today: copper-plated zinc. This change was made to further reduce production costs. The current penny weighs approximately 2.5 grams.
Here’s a summary of the different penny compositions:
| Composition | Years | Weight (grams) |
|---|---|---|
| Pure Copper | Prior to 1857 | 10.89 |
| Copper-Nickel Blend | 1857-1864 | 10.89 |
| Zinc-Coated Steel | 1943 | 2.7 |
| Copper-Plated Zinc | 1982 – Present | 2.5 |
As you can see, the penny has undergone various composition changes throughout its history, reflecting the evolving needs and circumstances of the time.
Weighing 100 Pennies
When it comes to determining the weight of 100 pennies, it’s important to consider the composition of the pennies in question. Prior to 1983, pennies were made of pure copper and had an average weight of approximately 3.11 grams each. In this case, 100 pennies would weigh around 311 grams.
However, since 1983, pennies have been made of copper-plated zinc, resulting in a slightly lighter weight. The average weight of a copper-plated zinc penny is around 2.5 grams. So, if you were to weigh 100 pennies made of copper-plated zinc, the total weight would be approximately 250 grams.
It is worth noting that individual pennies may have slight variations in weight due to manufacturing tolerances. These variations can be caused by factors such as the placement of the copper coating on the zinc core. Therefore, it’s always a good idea to consider the accuracy of your scale when weighing pennies, especially if you need precise measurements.

Accuracy of Penny Weighing
When it comes to weighing pennies, accuracy is essential. The weight of individual pennies can have slight variations due to manufacturing tolerances, so it’s important to consider the precision of your scale. Most scales that measure to the nearest gram may not provide the level of accuracy needed for weighing pennies.
To obtain the most accurate measurements, it is recommended to use a scale that measures to the nearest hundredth of a gram. These scales provide a higher level of precision and can help you get accurate readings for the weight of individual pennies.
Another option for precise measurements is to use a calibrated laboratory scale. These scales are specifically designed to provide accurate measurements for scientific and research purposes. If precision is crucial for your penny weighing needs, a calibrated laboratory scale can be a reliable option.
It’s important to note that even with a highly accurate scale, there may still be some variations in the weight of each penny due to manufacturing processes. However, using a scale that offers precise measurements will help minimize any potential errors and provide more accurate readings.
“Accurate weighing is key when it comes to pennies. Don’t rely on scales that measure to the nearest gram, as they may not provide the precision needed. Opt for scales that measure to the nearest hundredth of a gram or consider using a calibrated laboratory scale for the most accurate results.”
