Banco del Ñuble was one of Chile's provincial private banks authorized under the 1860 banking law, operating out of Chillán in the Ñuble region. The American Bank Note Company supplied plates and printed notes for several of these smaller Chilean institutions during the late nineteenth century, producing work of a technical quality that the local banks could never have sourced domestically.

The bank was forced into liquidation following Chile's 1898 Ley de Bancos reforms, which systematically wound down the provincial private note-issuing banks in favor of centralized currency control. Notes outstanding at the time of closure were redeemable but few holders in rural Ñuble bothered — which paradoxically kept some examples in circulation far longer than they should have been.
