The bars measure 23mm by 45.1mm and weigh 1000 grains, or just over 2 troy ounces.Only set I could find like this. Inscribed to the previous owner. The box has wear please look at pictures. Many of the pieces were loose in the box when I received it and show some wear due to age. Please let me know if you have any questions.
