The question of how to clean gold coins is a tricky one. While there are many precautions you can take to minimize the chances of damaging your coin, there are still many potential hazards involved in the process that could all reduce its value. You should approach this task with consideration and care if you decide that you need to clean your gold coins.
Cleaning gold coins is not usually recommended. It takes an expert to understand how to clean a gold coin without damaging its delicate surface and intricate shape, and there can even be value in the patina it's developed. If you're thinking of selling your coins, it's worth noting that most purchasers would rather have a dirty gold coin than one that wasn't cleaned properly.
Gold is a very soft metal. Any details or fine edges that are present on the coin can easily get damaged if you apply too much pressure in the cleaning process. Improper use of chemicals can harm the coin as well. Even the oils on your skin are hazardous to a coin made from pure gold, so you should always avoid handling a gold coin with bare hands.
Using proper precautions, you may be able to gently clean your gold coins if you feel that they're excessively dirty. Consider both the benefits and potential hazards of cleaning gold coins carefully before you move forward with this project.
If you're planning to clean your gold coins at home, there are several steps that you should take to protect them during this process.
Take a minimalist approach to the cleaning process for your gold coins. Use only as many steps as necessary to get your desired finish. You don't always need to make gold coins shine, particularly if they're ancient artifacts. If your coin is particularly dirty, you may want a cleaned gold coin so that you can view the markings better, but you shouldn't attempt to scrub the coin until it looks like new.
Follow these steps to clean your gold coin, but stop the process and skip to the last two steps as soon as you feel that the coin has achieved the desired appearance.
If you have valuable or ancient coins, it's often best to turn to a professional service when you feel that the coins need to be cleaned and restored. An expert in coins and antiques may have access to specialty cleaning products and tools, as well as the knowledge and skill set to clean your coin safely.
Some professionals even use an ultrasonic tank to clean gold coins. The coin is submerged in water, then subjected to sound vibrations that loosen the dirt and debris without the need for any physical contact. This approach to cleaning your coins will help ensure that they stay in good condition and retain their value.
Proper storage will keep your gold coins safe and protected so you won't have to clean them often. In the appropriate packaging, your gold will never be exposed to dust, dirt or other elements that can accumulate on the surface or cause it to tarnish. Follow these tips for properly storing your gold coins:
Understanding how to properly clean a gold coin will help you tackle this project as safely as possible if you feel it's absolutely necessary to polish up your coin. Keep in mind, however, that ancient or historic artifacts will usually retain more value when left undisturbed, even if they're not pristine in their current state. Consider the reasoning for your project carefully so you can make a mindful and informed decision about whether and how to clean gold coins in your collection.
