Rev. VICTORIA AV?? I / CONOB Cross potent on base and three steps. DOC 187a (Alexandria). MIB 77 (Cyprus). SB 851 (Jerusalem). Sharply struck and with almost intact mint luster. Some striking flatness, otherwise, good extremely fine.

The place where this issue was struck has long been rather controversial. Given how tumultuous Heraclius' reign was, first the overthrow of Phocas and then the almost ceaseless war with the Persians, there was a real need for provincial/military mints to pay the military. This type, because of the curious short busts and the officina Ι, was, for a time, attributed to Jerusalem. That seems less likely now, but given how scholars are, it may well end up being re-re-attributed at some future date.
