100 Pesos Law of Aug. 14th., 1935

Uruguay's 1935 banking law was part of a broader effort to reorganize the republic's monetary framework after years of financial strain, and the Banco de la República Oriental del Uruguay — a state-owned institution since its refounding in 1896 — had long relied on Thomas De La Rue for high-security production it could not replicate domestically. This note carries the authorizing legislation date in its title rather than a simple series year, a practice that distinguished legal mandate from actual issuance, which in this case came two years later.

Pick 31 is not a rare note, but earlier dates in the series are harder to find in presentable condition due to heavy commercial use in Montevideo's active retail economy through the late 1930s.
