In the later years of his rule, Justin I, sensing his declining health, chose to designate his nephew as co-Augustus in order to ensure a smooth transition of power. This nephew, known as Flavius Justinianus, then assumed the throne, marking the beginning of the reign of one of the most significant early Byzantine leaders. Their joint rule endured for a brief period of around four months and resulted in the minting of only a few coins featuring both rulers.
