COLOMBIA. Banco de la República. ½ Peso Oro. July 20, 1935. P-384.An intriguing, one-year type and extremely rare in high grades. These were needed for change and hard used. Brown face and back. Caldas at left. This has six-digit serial number. The handling is light and the colors extraordinary. A lesser note, raw “VF,” in Lyn Knight’s June 2017 auction realized nearly $1,100. This beauty should eclipse that handily.
