Accepting requests from manufacturers or distributors of precious metal wares, the Mint examines the fineness of precious metal wares and certifies the fineness of such wares by stamping the following marks on all wares that pass this examination. Such a mark is commonly called a hallmark. Our certification wins the confidence of the general public and contributes much to the safety of precious metal wares trade.
