Some bullion products carry serial numbers, typically stamped on the bar or shown on an accompanying assay card.
Buyback pricing
Serial numbers do not affect our buyback prices. Buyback is based on metal type, weight, and purity, not the presence or absence of a serial number.
Record-keeping & auditing
Serial numbers may be useful for internal records, inventory tracking, or audit purposes (e.g. SMSF or business reporting), but they are not mandatory.
Authenticity considerations
Serial numbers can help support authenticity when combined with other checks, such as weight, dimensions, mint markings, and testing. However, serial numbers alone do not guarantee authenticity, as counterfeit products may copy genuine serial numbers.
