1/2 Real - Felipe IV Segovia,portrait

Felipe IV's half real from the Segovia mint occupies an odd corner of Spanish colonial-era monetary history — produced by the screw press at a mint that had been mechanized since the 1580s, it predates the endemic fraud and debasement scandals that would force Madrid to radically restructure Castilian silver coinage by mid-century. The 1631–32 window falls just as Olivares was squeezing every available revenue stream to fund simultaneous wars in the Low Countries, Germany, and Italy.

Segovia's water-powered mill machinery consistently produced sharper, rounder flans than the hand-hammered cobs coming from American mints — a distinction that made machine-struck pieces from this facility particularly easy to clip, prompting later ordinances requiring milled edges.
