Medal - Dos y Medio

The "Dos y Medio" — two and a half — designation places this among the fractional token and medal issues circulated as emergency or supplementary currency across Latin America and Spain during periods when small-denomination coinage was chronically undersupplied. Aluminium-zinc bronze alloys were adopted precisely because they were cheap to strike and resistant to corrosion in humid climates, practical virtues that mattered more than prestige.
