2 Reales Provincias del Rio de la Plata

The Provincias del Río de la Plata began striking silver coinage at Potosí in 1813 — the same mint that had supplied Spanish colonial silver for over two centuries — less than two years after the May Revolution of 1810 severed effective royal authority. Using the existing infrastructure while rejecting the crown was a deliberate political act. The new government needed hard currency immediately to fund military campaigns against royalist forces still holding Upper Peru.

KM#3 was struck only across those three years before the coinage was superseded by the 1815 series. Potosí itself fell back into royalist hands in 1815, ending production entirely.
