1000 Pesos Law of Jan 2nd., 1939 - Issued by BCU

By 1967, Uruguay was in the grip of a prolonged economic deterioration that would eventually force a complete currency reform — the 1000 Pesos denomination, once substantial, had been rendered nearly meaningless by inflation before the series was even retired. The legal authority cited on the note, the Law of January 2nd, 1939, predates the note's actual issue date by nearly three decades, a gap that reflects how Uruguayan monetary legislation was drafted with broad, open-ended mandates rather than issue-specific authorization.

Thomas De La Rue printed this series in London throughout multiple decades of continuous use, with relatively minor plate modifications between early and late printings — making precise date attribution on undated specimens genuinely difficult without serial prefix analysis.
