30 Nummi - Heraclius Constantinopolis

This issue falls within Heraclius's post-Persian War period, immediately following his celebrated recovery of the True Cross from the Sassanid Empire in 629–630. The Constantinople mint was reorganizing its bronze output in these years, and the 30 nummi denomination was already in structural decline — within a generation, the follis and its fractions would be simplified further under Constans II.

BCV 812 is among the scarcer Constantinople bronze types of the reign, with surviving examples frequently showing flat areas attributable to worn dies rather than circulation — a known characteristic of late Heraclian bronze production at this mint.
