1 Duarius - Leopold I

The duarius — a denomination peculiar to Hungary's copper-silver billon coinage — was kept in production through Leopold I's reign largely to address the chronic shortage of small change in a kingdom still economically fractured by 150 years of Ottoman occupation and near-constant Habsburg military campaigning. By 1699, the Treaty of Karlowitz had finally expelled the Ottomans from most of Hungarian territory, but the monetary infrastructure of the recovered regions was in ruins. These coins circulated hard in that vacuum.

The ÉH#1104a variety indicates a documented obverse die distinction within this short three-year window.
