Seiseno - Louis XIII Villafranca, lozenge shield

The 1642 date places this coin squarely within the Catalan Revolt — the Guerra dels Segadors — when Catalonia had renounced Philip IV of Spain and placed itself under French protection, acknowledging Louis XIII as Count of Barcelona. Copper coinage issued under Louis XIII's authority in Catalonia was a direct assertion of that new political arrangement, minted at Villafranca del Penedès as the conflict ground on. Louis XIII died in May 1643, making the window for his Catalan issues extremely narrow.
