2 Escudos - Felipe IV Segovia, shield not in circle

Felipe IV's reign saw the Spanish crown in near-continuous fiscal crisis — the Thirty Years' War, the Catalan Revolt, and the ongoing conflict with Portugal had drained Castilian finances to the breaking point by the 1650s. The Segovia mint, powered by its water-driven machinery installed under Felipe II, was one of the few facilities capable of producing machine-struck gold with consistent planchet quality. The "shield not in circle" variety distinguishes this emission from closely related die marriages of the same period, a detail that matters considerably to specialists working through the Calicó typology.
