40 Nummi - Heraclius Constantinopolis

By the time this issue entered circulation, Heraclius had just concluded the most grueling war in Byzantine history — a nearly three-decade conflict against Sassanid Persia that ended in 628 with the recovery of the True Cross. The Constantinople mint was simultaneously managing a currency in structural crisis: decades of military expenditure had degraded bronze coinage so severely that follis weights had collapsed from Justinianic norms, and this series reflects that debasement directly.

The DOC range 105–115 encompasses meaningful die variation across the decade, including regnal year markings that allow closer dating within the 629–639 window.
