5000 Pesos

Uruguay's severe inflation of the 1960s forced denominations upward so rapidly that the Banco Central, established only in 1967, was issuing notes at the 5000 peso level almost immediately. This note belongs to the brief final phase of the old peso system — in 1975, the government redenominated at 1000 to 1, effectively erasing four zeros and replacing the peso with the nuevo peso.

De La Rue produced the series in London under contract, a common arrangement for smaller Latin American central banks lacking domestic intaglio capacity at the time. The watermark is the sole security feature — modest even by late-1960s standards.
