1 Décimo

Chile's decimal coinage system was formalized under the monetary law of 1851, which replaced the old real-based system and aligned the country more closely with emerging Latin American monetary standards. The décimo denomination sits in the middle of that reformed structure, struck at the Santiago mint during a period when the Chilean state was actively consolidating its financial institutions following the turbulent 1850s — a decade marked by civil conflict, including the 1851 uprising against President Manuel Montt.

The KM#124a designation distinguishes this as the .900 fine silver iteration, separated from earlier alloy variants in the catalogues.
