20 Pesos Banco de D.Matte y Ca.

Banco de D. Matte y Cía. was one of several Chilean private banks operating under the 1860 Ley de Bancos, which permitted note-issuing rights to chartered commercial institutions. The Matte family banking house, connected to the powerful Santiago commercial elite, used the American Bank Note Company for its currency production — a common arrangement for Chilean private banks of the period, as ABNC's New York operation dominated South American banknote contracts through the 1880s and 1890s.

Chile's private banking era ended abruptly with the 1898 nationalization of note-issuing rights, after which most surviving private bank notes were redeemed and pulped. Uncirculated examples from this series are genuinely uncommon as a result.
