Costa Rica's fractional silver coinage of this period was struck at the Casa de Moneda in San José, established only in 1825 following independence from the Central American Federation. The 1/8 peso denomination served the practical needs of a coffee-export economy where small change was perpetually scarce — a chronic problem across Central America that drove several republics to maintain fractional silver long after larger denominations had migrated to other standards.

KM#102 spans five years of production, but surviving examples vary considerably by date, with certain years representing genuinely small emissions tied to silver supply disruptions from the domestic mines at Abangares.
