20 Nummi - Anastasius I Dicorus Constantinopolis, no Officina Letter, Small Module

Anastasius I's currency reform of 498 AD was one of the most consequential monetary reorganizations in Byzantine history — reintroducing large, clearly marked bronze denominations after decades of tiny, near-anonymous nummi that had made everyday transactions genuinely cumbersome. The 20 nummi piece was part of that reformed system, its value mark intended to eliminate ambiguity at point of exchange.

Constantinople issues lacking an officina letter represent an early and transitional phase of the reform, before the mint settled into consistent workshop identification practices. The small module distinguishes these from later, heavier strikes of the same type.
