8 Maravedis - Felipe IV Segovia,milled

Felipe IV inherited a copper coinage problem he didn't create. The milled 8 maravedís produced at Segovia in the early 1620s were part of a broader effort to replace the poorly controlled hand-struck vellón that had flooded Castile under his father — coins so easy to counterfeit that private forges in Portugal and France had been supplying them for years. The Segovia mint, powered by the Eresma river's hydraulic machinery, was one of the few Spanish facilities technically capable of producing consistent milled copper at scale.

This series was suspended by the pragmatic of 1626, which drastically resized the vellón coinage. Pieces from this short window were subsequently overstruck in later revalidation campaigns, making unaltered survivors harder to find than mintage alone would suggest.
