A certificate of assay for gold bars is an official document that verifies the authenticity and purity of the gold. It typically includes details such as the weight, fineness (purity), refiner's mark, and a unique serial number of the gold bar. This certificate assures buyers and sellers of the bar's value and quality, often issued by a reputable assay office or refinery.
