10 Pesos Iglesia de Boyá

The Iglesia de Boyá, located in the municipality of Monte Plata, is widely considered the oldest surviving church in the Americas still standing on its original foundations — a claim that puts it in direct competition with several other colonial-era structures across the Caribbean. The Dominican Republic has returned to it repeatedly as a subject for commemorative issues, treating it as a fixed point of national historical identity rather than a rotating theme.

The .9999 fineness is atypical for a circulating-denomination commemorative of this size; most regional gold issues of the period settled at .900.
