50 Centavos Provisional Government

The State of Oaxaca struck its own coinage during the Mexican Revolution after the state government, under Governor José Inés Dávila, refused to recognize Carranza's Constitutionalist authority and declared itself a sovereign entity in 1915. These provisional issues were a direct assertion of regional autonomy at a moment when central monetary authority had effectively collapsed — multiple factions were simultaneously issuing currency, and much of it was refused at gunpoint in the markets of rival-controlled territories.

Oaxacan silver issues are notably cruder in execution than contemporary federal strikes, a consequence of improvised minting infrastructure rather than any shortage of the metal itself.
