Wiedenbrück's copper small change from this period falls into the category of Notmünzen — emergency or necessity coinage struck by municipal authorities when the supply of small imperial coin was inadequate for local commerce. The Westphalian linen trade depended on petty transactions, and towns like Wiedenbrück frequently filled the gap themselves. Kennepohl's listing of this type under #520b distinguishes it from closely related varieties in the sequence, a distinction that matters given how freely these civic issues were imitated and counterfeited across the region.
