4 Gute Pfennig

Brunswick's municipal coinage operated in persistent tension with the duchy surrounding it — the city maintained its own minting rights as a quasi-independent imperial city even as the Welfen dukes pressed for consolidation. The 1670s issues, including this piece, came during a particularly fraught period: the city had only recently resolved a prolonged constitutional dispute with Duke Rudolf August, and the right to strike coin was itself a marker of that hard-won autonomy.

Jesse 288 places this squarely within a short emission window. The 4 Gute Pfennig denomination was a practical subdivision for local commerce, not interregional trade.
