Assay Certificate of Authenticity (COA) Defined

An assay is an analysis designed to measure and test the composition in ore, alloys, and precious metals. With respect to precious metals, specifically silver and gold, it is a way to make sure that all the coins or bars produced in a mint meet the correct purity standards and example, if a mint promises that a gold bar has percent purity, an assay is necessary to make sure
