20 Pesos Banco de Curicó

The Banco de Curicó was one of Chile's provincial free-banking era institutions, operating under the Ley de Bancos of 1860 which permitted regional banks to issue their own notes backed by metallic reserves held with the government. ABNC engraved and printed paper for dozens of Latin American clients during this period, supplying finished sheets to issuers who often lacked domestic printing infrastructure capable of the intaglio security work.

The "r" suffix in the Pick reference denotes a remainder — unissued stock, never signed or serialled, returned or retained rather than put into circulation. Curicó province was a wine and agricultural center; whether the bank ever fully distributed its authorized note supply is unclear from surviving records.
