8 Reales Type I Countermark

Costa Rica's first decade of independence produced no functioning mint, leaving the republic dependent on foreign silver for daily commerce. The solution was pragmatic: Spanish colonial 8 reales hosts were countermarked at the Casa de Moneda in San José to give them official domestic standing. The Type I punch — applied across 1841 and into 1842 — is distinguishable from the later Type II by die characteristics that specialists have catalogued extensively, though attribution on worn hosts can be contentious.

Host coins vary considerably, drawn from Guatemalan, Mexican, and South American mints. The countermark itself is the only element under Costa Rican authority.
