Gold Bar Specifications at Fort Knox
The specifications of each gold bar at Fort Knox follow internationally recognized standards to ensure consistency and trust. These bars are not arbitrary in size or weight; they are produced to meet the strict guidelines of the London Good Delivery list, which many central banks rely on.
