10 Nummi - Justin I Constantinople

Justin I came to power in 518 as an illiterate Macedonian soldier who relied heavily on his nephew Justinian to manage administrative affairs — the 10 Nummi fraction being among the smallest bronze denominations struck under his name. The Constantinople mint was the dominant production center throughout his reign, with provincial mints at Nicomedia and Thessalonica playing secondary roles.

BCV 71 covers considerable die variation within the type, and attributing individual pieces precisely within the 518–527 span remains difficult without strong officina marks.
