1 Peso Pattern

Argentina's monetary system in 1880 was a fractured mess of provincial issues, foreign coins, and paper notes circulating at wildly inconsistent rates. The national government was pushing hard for a unified coinage, and pattern strikes like this one were part of that effort — proposals submitted for official consideration that never made it to full production. The 1 Peso denomination in this weight and fineness would have aligned Argentina with the Latin Monetary Union standard, a deliberate signal of international credibility the country was anxious to project.

KM#Pn20 is among several patterns documented from this period, most surviving in very small numbers held by institutional collections.
