⅔ Thaler

Emden's municipal coinage of the late seventeenth century reflects the city's persistent struggle to maintain monetary autonomy against the encroachments of Brandenburg-Prussia, which had claimed suzerainty over the city since 1660. The ⅔ Thaler — equivalent to the Gulden or two-thirds piece dominant in northern German trade — was the workhorse denomination of the period, widely accepted across the Hamburg-based exchange networks.

KM#31 is among the later civic issues before Emden's coinage rights were effectively curtailed in the early eighteenth century.
