Einbeck's municipal coinage of the 1570s was struck at a moment when the city's brewing trade — the origin of "Einbeck" beer, the precursor to Bavarian Bock — still underwrote considerable civic wealth, though the town's political autonomy within the Holy Roman Empire was already being squeezed by Brunswick-Wolfenbüttel. The Buck reference places this among a tightly documented run of municipal groschen, with the Ei#46k designation distinguishing a specific die state within a short production window of just three years.
