10 Nummi - Justinian I X, Rome

Rome returned to Byzantine hands in 536 after Belisarius took the city from the Ostrogoths, but the mint there operated fitfully — interrupted twice by Gothic recapture, in 546 and again briefly in 549-550. Coins struck at Rome during Justinian's reign are consequently far less uniform than those from Constantinople or Thessalonica, with the Roman workshop producing in smaller volume across a prolonged and militarily disrupted occupation.

MIB I#244 places this type firmly within the Roman mint's output, distinguished from eastern products by subtle fabric differences rather than explicit mint marks.
