In Alexandria during the Byzantine era, they minted an usual denomination of 12 nummi called "dodecanummi". You can recognise it by seeing the "IB" on the reverse. Byzantines did it because there were already coins with "IB" prior in Alexandria I have been told. Can one here please show me how they looked like and what they were called? Did Ptolemaic Kingdom and Roman Empire before the 395-split issue coins or weights with the sign of "IB" on it ? I want to search it, but I have no clue. Did the Macedons and Romans (not "byzantines") struck coins with "IB"? Thanks
I don't exactly understand your question. Justinian might have been the first to make this denomination? Heraclius Mint: Alexandria 610 to 641 AD AE 12 Nummi Obvs: Draped and cuirassed bust facing, wearing crown surmounted by cross within crescent. Eight-rayed star to left, crescent to right. Revs: Large IB, cross on globe between. AΛЄΞ 18mm, 6.38g Ref: Sear 855
"I don't exactly understand your question. Justinian might have been the first to make this denomination?" No. I think the Macedonians and Romans before 395 did issue coins with "IB" on it. Perhaps others know it.
Appearently no. Perhaps I should change my question: Did the Macedonians and Romans issue coins with a denomination with the number of "12", or in a way that resembled like the Alexandrian one posted by David@PCC ? I am not expecting anything.
