20 Pesos Banco de Pamplona

Banco de Pamplona was one of the short-lived regional banks chartered under Colombia's 1865 banking legislation, operating out of Norte de Santander during a period when note-issuing rights were genuinely decentralized. The bank's circulation window was narrow — federal monetary reforms in the 1880s were already tightening the conditions under which provincial banks could operate, and most ceased issuing well before the Banco Nacional consolidated control later in the decade.

Bradbury Wilkinson's involvement places the production squarely in their standard export banking work of the period, supplying engraved notes to smaller institutions across Latin America that lacked local intaglio capacity. The Hernández reference number suggests this is among the earliest documented issues from the bank.
