20 Colones Banco Anglo Costarricense

Banco Anglo Costarricense was the oldest commercial bank in Central America, founded in 1863 with British capital and operating under a government concession that permitted private note issue well into the twentieth century. This series ran across a notably long window — eight years — during which Costa Rica's banana export economy was expanding rapidly, making 20-colón denominations genuinely functional in large agricultural transactions rather than merely ceremonial tender.

Bradbury Wilkinson's involvement is worth noting: the London firm held contracts across dozens of Latin American issuers simultaneously, and their intaglio work for the Anglo Costarricense series was among the finer examples they produced for the region during this period.
