1 Barillo Uniface pattern

The barillo was a fractional copper denomination proposed for colonial Philippine circulation under Spanish authority, and pattern strikes like this one were produced to demonstrate viability before full authorization. The uniface format — struck on one face only — indicates this was an early production test rather than a presentation piece. Whether Manila ever received approval to proceed with regular coinage of this denomination remains unclear; circulating copper for the Philippines in this period was largely sourced from Mexico or improvised locally.
