100 Baht

Thailand's post-war monetary reconstruction moved quickly after the 1947 coup that brought the military back to power, and this series reflects that political urgency — the government needed credible, professionally produced currency to stabilize confidence after years of wartime disruption and occupation-era Japanese-sponsored baht issues. Thomas De La Rue in London was the natural choice; Bangkok lacked the infrastructure for high-security production at scale.

Pick 73 is scarcer than its catalogue position might suggest. The series had a relatively short issue life before being superseded, and tropical storage conditions in Thailand are notoriously hard on cotton-paper notes of this period.
