40 Nummi - Anastasius I Dicorus Constantinopolis, Type ✶M✶, Small Module

Anastasius I's currency reform of 498 AD was among the most consequential monetary reorganizations in late antique history, reintroducing large-denomination bronze coins after decades of tiny, almost valueless nummi had dominated everyday exchange. The 40-nummi follis was the flagship denomination of that reform. This small-module variety, however, represents a transitional or supplementary emission — the weight reduction from the earlier, heavier folles reflects ongoing adjustments in the years following the initial reform as the mint at Constantinople calibrated output to metal supply and economic demand.
