Assay Certificate
An assay certificate is an official document issued by the mint or refinery guaranteeing a bullion product's metal content, weight, purity, and serial number.
What an Assay Typically Includes
- Product name and description
- Metal purity fineness
- Gross and fine weight
- Unique serial number matching the bar's engraved number
- Refinery name, logo, and authentication signatures
- Security features (holograms, QR codes)
Assayed vs. Non-Assayed Products
Premium products from PAMP Suisse, Valcambi, Perth Mint, and the Royal Canadian Mint include proprietary assay packaging. Generic rounds and secondary market bars are sold without individual assay documentation.
