1 Peso Provisional Government

The State of Oaxaca began issuing its own silver coinage in 1915 after the state government under José Inés Dávila broke from the Carranza faction and declared itself a sovereign entity — the "Soberanía de Oaxaca" — refusing to recognize Carranza's constitutionalist currency. The result was a series of locally struck provisional issues using whatever silver could be procured, with quality and alloy consistency varying noticeably across the run.

KM#743 is among the heavier pieces in the Mexican Revolutionary series, and the weight reflects an attempt to maintain parity with pre-revolutionary Peso standards rather than the debased issues circulating elsewhere in Mexico at the time.
