text: Again, sorry for the distraction Just about everyone knows about the first AD dated coins (Roskilde 1234), and a lot of people know about the first coins dated in European "Arabic" numerals (St-Gallen 1424).But of course the Muslims were dating coins in their own Arabic numerals well before 1424 AD; I have one example that (probably) dates from 723 AH = 1323 AD, and, IIRC, yet earlier dates are known.
