5 Pesos El Banco de Tamaulipas

El Banco de Tamaulipas was one of the regional banks authorized under Mexico's 1897 Ley General de Instituciones de Crédito, which allowed individual states to charter note-issuing banks under federal supervision. The arrangement gave northern border states like Tamaulipas real monetary infrastructure during the Porfiriato's commercial boom — but the entire system collapsed when Carranza's 1916 decree abolished all state bank currency, rendering these notes worthless overnight.

The American Bank Note Company's involvement was typical of the period's prestige signaling; Mexican regional banks competed for ABNC contracts partly because the New York imprint carried credibility with merchant communities skeptical of provincial paper.
