| Additional information |
The Casa de Moneda de San José — Costa Rica's national mint, established in 1825 — produced this series during a period when the young republic was still negotiating the practical realities of monetary independence from the collapsed Central American Federation. The dual denomination, expressing value simultaneously in the old Spanish escudo system and the emerging decimal onza, reflects that transitional awkwardness directly in the coin's name rather than resolving it.
KM#100 is known with multiple assayer initial combinations across the 1850–1858 run, and attribution without confirmed assayer marks can be genuinely difficult.
