1000 Reis - Maria II

Maria II reclaimed the Portuguese throne in 1834 following a protracted civil war against her absolutist uncle Miguel, and the monetary system she inherited was in considerable disorder — years of conflict had disrupted minting operations and eroded public confidence in coinage. This 1000 Reis issue was part of a broader currency reform intended to stabilize the realm's finances in the immediate post-war years.

The high silver fineness of .91666 — the old Portuguese monetary standard — was retained rather than adopting the more modern .900 fine standard gaining ground elsewhere in Europe, a conservative choice that reflected both metallurgical tradition and the political caution of a government still consolidating power after a dynastic war.
