Being able to authenticate your gold and silver before you buy it is a cornerstone to successfully buying gold and silver. Simply put, it is something you must be able to do. Keep in mind that authentication is more than determining if the bullion is real… it is also about determining purity.
There are pros and cons to each method of authentication based on factors such as ease, accuracy, portability, and cost. Here are the ways to authenticate gold and silver:
A chemical, or acid test, is a test that uses acid as an authentication agent. Acid testing can be used to authenticate gold, silver, or platinum. It determines authenticity and purity based on how the metals react to different concentrations of acid.
Electronic testers utilize technology. Some electronic testers fully electronic, and others require manual processes for the preparation of the test. Electronic testers read and display results using an electronic device. Different categories of electronic testers have different abilities in terms of the purity they are capable of determining.
Ultrasonic testing is a form of electronic testing, and it is primarily used for testing gold bars. This technology works by shooting ultrasonic waves into the gold bar.
X-Ray Fluorescence Testing (XRF)
X-ray fluorescence is an electronic testing method, that works by exposing the sample with radiation. X-ray fluorescence is commonly called XRF.
It is important to also mention that there are smartphone apps available for authenticating gold and silver. A word of caution though, as some do not meet their clams.
There are also manual authentication devices that test bullion coins. They work by verifying the size and weight of coins, as well as by sound (by “ringing”).
Your authentication method(s) should correspond to the type of purchasing you are doing.
