1 Peso Pattern

Costa Rica's monetary situation in 1850 was genuinely chaotic — the young republic was still operating with a patchwork of colonial-era reales and foreign coins when this pattern was struck. The peso denomination itself was aspirational, reflecting Central American federation-era currency ambitions that had largely collapsed by then with the dissolution of the Federal Republic of Central America in 1839.

White metal patterns of this period were typically struck in small quantities for government approval, and KM#Pn2 never advanced to circulation. The composition itself — likely a tin or pewter alloy — was a practical choice for a proof-of-concept piece rather than a production proposal.
