1/2 Groten Thick flan pattern strike

Bremen's municipal coinage in the late eighteenth century occupied an awkward administrative position — the city retained its independent minting authority as a Free Imperial City, but that status was increasingly under pressure from both Hanoverian territorial ambitions and the broader rationalisation of German monetary systems. Pattern strikes like this one were typically produced to test die alignment, planchet thickness, and press tolerances before committing to a full production run. The thick flan specification here suggests the city was evaluating an alternative module that was ultimately not adopted.
