How Gold Bars Are Checked
Before buying or selling a gold bar, learn what a professional provider may inspect. Visible markings, packaging and paperwork can help identify an item, but appearance alone cannot prove authenticity.

About how gold bars are checked
A bar may carry a refiner name, fineness, weight and serial number. Some are sealed in assay cards; others are cast bars with a different finish. A provider chooses suitable physical or instrumental verification methods according to its own process.
Prices, checks & considerations
Avoid relying on a home visual check to guarantee a bar is genuine. Ask the independent provider how authentication works and whether it affects the appointment or final offer.
Before your Hatton Garden enquiry
- 01Record all visible markings and the stated weight

Frequently asked questions
Does an assay card guarantee a genuine gold bar?
No. Packaging is supporting information, not a substitute for independent verification.
Should I scratch or cut my bar to test it?
Do not damage the item as a DIY test; ask the trading provider how it assesses authenticity.
