20 Centavos Tetela del Oro y Ocampo

Tetela del Oro y Ocampo was one of dozens of Mexican municipalities forced to produce emergency coinage during the Revolutionary period, when the collapse of the national monetary system left local economies without functional small change. The Constitutionalist, Villista, and Zapatista factions each controlled different regions at different moments, and federal coinage had effectively ceased to be trusted or available in much of rural Puebla by 1915.

KM#764 is among the more obscure municipal issues — Tetela was a small mining district, and its copper output was almost certainly limited to immediate local need rather than any broader circulation.
