Medina, J.T. LAS MONEDAS OBSIDIONALES DE CHILE. Santiago de Chile: Imprenta Elzeviriana, 1919. 4to [31 by 22.5 cm], original printed card covers. 36, (4) pages; title printed in red and black; halftone text illustrations. Minor foxing to covers and margins; near fine. A separately published excerpt from his broader Las Monedas Obsidionales Hispano-Americanas. One of 150 copies printed, this is untrimmed and in its original state. Roberts notes: “Medina called ‘obsidional’ those moneys which owed their origin to a state of war or other unusual circumstances. He described them in detail, much as he described the medals in his collection, and reproduces photographic copies of many of them.” Behar 3524. Burzio Centenario 81. Clain-Stefanelli 8602.
