Banco Internacional was a short-lived Mexican private bank, one of several chartered during the Díaz-era liberalization of banking that preceded the Banco de México monopoly by four decades. The American Bank Note Company's Mexico City client list was crowded by the 1880s, making this a competitive commission rather than an exclusive arrangement.

P#S648 falls within the "S" prefix of the Pick catalog — the chartered but privately issued series — which itself signals how fragmented Mexican note-issuing authority remained before the 1897 Ley General de Instituciones de Crédito imposed some order on the system.
