1/25 Onza Cacao

The Onza Cacao series was introduced by the Casa de Moneda de México as a direct nod to pre-Columbian Mesoamerican economies, where cacao beans functioned as genuine currency among the Aztec and Maya. The fractional denominations — including this 1/25 piece — were struck in limited quantities and never achieved wide circulation, existing primarily as collector issues rather than transacting coinage.

The 18-karat composition is unusual for a modern Mexican bullion-adjacent issue, which typically favors .999 fine gold.
