[QUOTE="EWC3, post: 4605394, member: 93416"]Facinating – thanks! - opens all kinds of doors Led me to this which I had not seen before [URL]https://www.livius.org/pictures/iran/persepolis/persepolis-treasury/persepolis-treasury-weight-dwc/[/URL] at 120 Karsha = 9950g yields = 20 mina = thus a mina of 497.5g (note the small chip on the base) The BM official weight of Darius (1/3 mina) weights to a mina standard of 500.19g Since the BM weight is perfect it looks like the achieved accuracy might have been better than 0.5% on this 10 KG weight…..(!) Has anyone seen this investigated further? These days it would be easy to scan and model the Persepolis piece and calculate its pre-damage weight.
