Follis - Constans I VOT XX MVLT XXX, Heraclea

The VOT XX MVLT XXX votive legend marks a specific dynastic moment: the twentieth anniversary of Constans I's rule being celebrated with vows anticipating a thirtieth. These anniversary issues of 347–348 were struck simultaneously across multiple mints as a coordinated imperial statement, part of the broader currency reform that also produced the heavier centenionalis. The Heraclea mint, operating under the diocese of Thrace, was one of the more active participants in that reform.

At 12 mm and under two grams, these pieces circulated hard and typically show it.
