COA & ASSAY
When collecting or selling bullion or coins, you may have noticed that some items come in an assay card, or are accompanied by a certificate of authenticity. In the bullion industry, the definition of assaying has two meanings. In precious metal refining, an assay process is a test procedure for measuring and analyzing the purity of a metal. This procedure includes determining its composition in ores, alloys, mineral deposits and precious metals. This way mints assure that the bullion meets its precious metal standards of content and purity.
What Is The Difference Between Silver And Sterling Silver?
What is the difference between silver and sterling silver? Have you ever seen these numbers – 900, 925, 999 or 9999 – on your jewelry piece or bullion item? Some of you probably still wonder what they show or stand for.
Silver is a precious metal which you won’t find in nature in a 100% pure form. This means that we need to extract it from various ores or mix it with galena and argentite. To offer silver the well-known shape, the ores undergo several refining processes. These processes separate the silver from all other types of particles. Namely, the complexity of these refining actions is the key factor that defines the fineness (and value) of silver. Thus, the first four numbers, the silver grades, showcase the amount of fine silver in a specific precious metal piece. For instance, 900 means 90% pure silver, while the remaining 10% indicate that it consists of other metals.
The maximum purity can reach up to 99.99% or .9999 fineness. But the most popular highest silver purity is 99.9%, .999 or 999 – all three being the same, differing only by scale/notation. Silver with .999 fineness is called fine silver, actual silver, or pure silver; 99.99% pure silver – ultra-fine silver. Therefore, the silver having less than .999 fineness is sterling silver, being usually 92.5% pure.
