Ducat

Zürich's civic ducats of the mid-seventeenth century were struck against a backdrop of sustained pressure on Swiss city-states to maintain independent monetary credibility following the disruptions of the Thirty Years' War, which had ended just over a decade before this piece was produced. The city jealously guarded its minting rights, and these gold issues circulated well beyond cantonal borders into the broader German trade network precisely because Zürich's weight standards were trusted where many German issues were not.

The 1662 date places this within the "q" variety as catalogued by HMZ 2-1138, a distinction tied to die differences in the city arms rendering rather than any major design departure.
