1987 Peru 50 Intis Banknote Nicolas de Pierola Oil Rig P-137 Note

Issued by the Central Bank of Reserve of Peru (Banco Central de Reserva del Perú) under the printed authorization date of June 26, 1987 (26 de Junio de 1987), this legal tender 50 Intis banknote (Cincuenta Intis) was printed by the state security printer Casa da Moeda do Brasil. Cataloged internationally in the Standard Catalog of World Paper Money as Pick #137 (P-137) and The Banknote Book as B444, this orange, brown, and multicolor emission represents the monetary transition era of the Peruvian Inti introduced during the administration of President Alan García. The obverse features an engraved portrait of Nicolás de Piérola (1839–1913), former President of the Republic and Commander-in-Chief during the War of the Pacific, positioned alongside the national coat of arms of Peru, an ancient pre-Columbian ceremonial vessel motif, and the authorized facsimile signatures of the Director, Presidente, and Gerente General. The reverse highlights the nation's energy sector and natural resource extraction in the Amazon basin, depicting an active petroleum exploration platform where oilfield roughnecks maneuver heavy drill pipe casing alongside an oil derrick and a transport helicopter in flight. Security architecture incorporates microprinted typography, fine-line guilloche background lathework, localized watermarking, and letterpress serial numbering with series prefix A and suffix Q. This banknote serves as an essential type specimen for numismatic collections focusing on South American economic history, Latin American political leadership, and industrial petroleum motifs.
