Refined in .999 fine silver and stamped with an individual serial number, each bar reflects the craftsmanship and credibility of a historic brand no longer active in bullion production. JM bars remain widely recognized thanks to their consistent weight, purity, and long-standing reputation among collectors and major vaulting facilities.
