Many reputable gold refiners, such as PAMP Suisse, Valcambi, and Asahi Refining, issue 1 oz gold bars with unique serial numbers and an assay certificate verifying their purity and authenticity. Some bars even come in tamper-evident packaging with built-in security features to prevent counterfeiting. While not all gold bars have serial numbers, purchasing from a trusted dealer like Bullion Exchanges ensures you receive a certified product with guaranteed quality.
