Coesfeld's copper pfennig coinage of this period represents municipal emergency money in the truest sense — the city, a member of the Hanseatic League in decline, issued small-denomination copper to plug gaps left by chronic shortages of small imperial coinage throughout the Westphalian region. The Thirty Years' War (1618–1648) fell almost precisely within this issue's long production window, during which standard coin supply collapsed across much of the Holy Roman Empire and local authorities routinely filled the vacuum with their own copper.
The 105-year span attributed to KM#5 suggests multiple die marriages under a single catalog number rather than continuous uninterrupted production.
