200 000 Nuevos Pesos

Uruguay's 200,000 Nuevos Pesos was one of the highest denominations issued before the 1993 redenomination that replaced the Nuevo Peso at a rate of 1,000 to 1, creating the Peso Uruguayo. The sheer size of the face value reflects the cumulative inflation that had eroded the original Peso Uruguayo through the 1970s and 1980s — the "Nuevo" prefix had itself been introduced in 1975 precisely to reset a currency already damaged by inflation.

De La Rue's involvement was typical of Uruguayan note production during this period, though the series carries only a watermark as its primary security feature — sparse by contemporary standards.
