Dipping my toes into Byzantine coinage. What is the earliest Regnal Dated coin for Justinian I? My earliest is XII or 12.0 Is there anything earlier? I really like those large and heavy bronzes. Post any Regnal dated bronze Follis from Justinian I.
With all of the Byzantine collectors on the forum, I would have thought someone would have an answer. 135 looks but no answer. Any suggestions on where I could to find the answer?
The coin reform of Justinian that introduced the facing bust and regnal-year dating was in year 12 at some mints, including Constantinople, and didn't begin until year 13 at others, for example Antioch and Carthage. Get a copy of the second edition (don't get the first edition) of Sear's Byzantine Coins and Their Values". It has a ton of information including which mints issued which years with which officina.
