How to check the serial number of a gold bar
Perform authenticity tests before investing your hard-earned money in gold bars to avoid counterfeits. It’s best to shop in person to closely examine the bullion bars.
More importantly, buy gold bars that were minted at trusted minting facilities.
Here are three easy steps to help you determine if a gold bar is real using its serial number.
Find the serial number on the gold bar.
Generally, gold bars display valuable information on the front or back.
Scan these inscriptions carefully. A gold bar’s serial number consists of letters and numbers denoting the manufacturer.
For example, you may find the unique serial number of gold bullion below the refiner’s logo, bar weight, and metal purity.
Contact the issuing authority.
After identifying the serial number, call the mint or refinery that created the gold bar. Provide the serial number to the issuing authority. They will tell you about the product’s authenticity and other essential information.
Some of the most trusted bullion manufacturers are PAMP Suisse, Valcambi, and the Royal Canadian Mint. These world-renowned gold refineries are reputable for producing high-purity gold bars.
Verify the serial number against a database.
Some mints and refineries maintain databases of gold bars with their serial numbers. Look up a gold bar’s serial number in the refinery’s database to ensure you are not buying a counterfeit.
PAMP Suisse developed a modern technology that allows investors to authenticate gold bars using the Veriscan mobile app, which allows users to verify authenticity by scanning the surface of a gold bar.
