Introduction
Before the introduction of paper money, people used a variety of coins as currency, including copper pennies. Pennies were first introduced in the US in 1792 and have been used ever since. While most people think of pennies as small change, they can have significant historical or sentimental value. That’s why cleaning pennies is important to preserve their aesthetic. This guide will provide you with tips and tricks on how to clean pennies safely and effectively.
The Ultimate Guide to Cleaning Pennies: Tips and Tricks
Reasons why pennies become dirty and corroded
Like any other metal, pennies are prone to corrosion. Oxidation occurs when a chemical reaction between copper and the oxygen in the air occurs, leaving a greenish layer of copper carbonate. Dirt and oil can also accumulate on the surface of the penny, giving it a dull appearance. This can happen to any penny, regardless of its age or history.
How to identify dirty pennies
If a penny looks dull, with a brown or greenish tint, it is probably dirty and corroded. However, some pennies may have rust or dirt build-up, which can be difficult to remove. It’s essential to identify the type of dirt or corrosion on the penny before deciding how to clean it.
Importance of cleaning pennies
Cleaning pennies doesn’t only make them look shiny and new but also preserves their aesthetic value. If you’re considering selling a rare penny, for example, cleaning it can improve its value.
Historical Value of Old Pennies and How to Clean Them
Historical significance of old and rare pennies
Pennies minted before 1982 are made of 95% copper and 5% zinc; they are worth more than their face value because of the value of their copper content. Old and rare pennies, like those minted before 1930, can be worth thousands of dollars. It’s crucial to understand their worth and identify which type of cleaning method will protect the coin’s value.
How to clean old pennies without causing damage
Cleaning old pennies is a delicate process and should not be treated like ordinary coins. Using abrasive or acidic cleaners can damage the coin’s surface and reduce its value. The best way to clean old pennies is by gentle mechanical and chemical methods, focusing on preserving the coin’s original condition.
Reasons why you shouldn’t clean certain old pennies
Old and rare pennies should not be cleaned if they have a collector’s value. Cleaning them may cause damage, thereby decreasing their value. They may have specific markings or clean lines that define their value. Cleaning may smudge or damage them beyond repair.
DIY Methods to Clean Your Pennies at Home

Lemon juice is also a useful tool to remove dirt with the acid, while also leaving a nice shine. Baking soda also works well- mix three parts baking soda to one part water and use the solution to clean the penny- but be sure to rinse it thoroughly.
Pros and cons of using DIY methods
The main advantage of DIY methods is that they are cost-effective and easy to use.

Baking soda or lemon juice can also be used in a similar process, but it’s important not to use these substances for an extended period to avoid damaging the coin.
Tips and tricks for achieving the best results
It’s best to use soft-bristled brushes or cloth, especially with old and rare pennies, to avoid scratches. For stubborn dirt build-up, immerse the coin in a cleaning solution for a short time, then rinse thoroughly and avoid rubbing with anything other than a cloth. Do not soak for too long in a cleaning solution as it could tarnish the coin’s surface or reduce its value.
