1 Groten

Bremen struck these small silver Groten throughout the early years of the Thirty Years' War, a period when the city's status as a Free Imperial City made it a target of competing imperial and Danish ambitions. The nearby conflict disrupted trade along the Weser, placing real pressure on the municipal treasury to maintain a reliable small-denomination currency for local commerce.

KM#78 encompasses several die variants across the four-year span, as Bremen's mint worked with multiple engravers during this period of intermittent wartime disruption.
