40 Bolívares

The Banco de Maracaibo was one of Venezuela's few regionally chartered private banks to survive into the twentieth century with note-issuing privileges intact. By 1915, it operated in an environment where the Caracas-based government had repeatedly failed to establish a stable central bank, leaving institutions like this one to fill the void in the Zulia region — Venezuela's commercial gateway to Lake Maracaibo and the nascent petroleum trade.

ABNC produced this denomination alongside the rest of the Banco de Maracaibo series under contract, a routine arrangement for Latin American private bank issues of the period. The 40-bolívar face value is the genuinely odd detail here: it fits no logical decimal sequence and almost certainly reflects a specific regional commercial convention or debt-settlement denomination rather than standard monetary planning.
