| Additional information |
The Real Ingenio de Segovia was one of the first mechanized mints in the world, powered by the Eresma river and producing milled coinage from the 1580s onward — a full century before most European mints adopted similar technology. By the reign of Carlos III, the facility was well past its innovative prime but remained the principal source of small copper for Castile.
Carlos III's monetary reforms of the 1770s rationalized the maravedí coinage after decades of chaotic resellado issues had left Spanish copper circulation nearly illegible. This 4 maravedis was part of that cleanup — a deliberate, administratively-driven recoinage rather than an organic production run.
