1 Nuevo Peso Overprinted on 1 000 Pesos

Uruguay's 1975 monetary reform lopped three zeros off the peso, converting 1,000 old pesos to 1 nuevo peso overnight. Rather than commit immediately to an entirely new print run, the Banco Central authorized overprinting existing Thomas De La Rue stock — a stopgap that produced an awkward hybrid note carrying the ghost of the old denomination beneath the new one.

The overprint itself is the collecting interest here. Alignment inconsistencies between examples are common, a predictable consequence of applying a secondary impression to already-finished notes.
