2 Escudos - Isabel II

These escudos belong to the decimal coinage system Spain adopted in 1864 under the Monetary Law of June that year, which replaced the old real system in an attempt to align Spanish currency with the emerging Latin Monetary Union. The timing was politically precarious — Isabel II's reign was collapsing under the combined pressure of military conspiracies, clerical opposition, and the economic fallout of the 1866 financial crisis that devastated Madrid's banking sector.

The series ended abruptly when the Glorious Revolution of September 1868 sent Isabel into exile in France, making the final-year strikes among the shortest-lived issues of the denomination.
