1000 Baht / 1000 Ticals Series 1, Type III with bottom serial

The Series 1 notes were Siam's first Western-style government banknotes, introduced following the Currency Act of 1902 which transferred note-issuing authority from the Royal Treasury to the newly established paper currency department. Thomas De La Rue printed the entire series in London, a relationship that reflected both the colonial-era influence on Siamese financial administration and the absence of any domestic printing capability capable of meeting European security standards at the time.

The Type III designation within this series distinguishes serial number placement — bottom serials appearing on later printings as the government refined its numbering conventions. At 1000 Ticals, this is the highest denomination in the series, meaning relatively few were struck and genuine circulation examples are exceptionally rare.
