Seiseno - Principality of Catalonia VNIVERCIS

Terrassa's copper seiseno dates to the Corpus de Sang — the June 1640 uprising in which Catalan harvesters murdered the Viceroy of Catalonia, triggering a war that would see the Principality formally place itself under French protection by January 1641. Municipal copper coinage flooded out of Catalan towns during these years partly because the break with Castile severed normal monetary supply chains, and partly because the cost of fielding troops demanded small-denomination liquidity fast. Terrassa was one of dozens of municipalities authorized to strike under the emergency monetary regime of the Generalitat.
