1000 Baht Series 15, Type 1

Thailand's Series 15 was launched in 1999 largely to introduce improved anti-counterfeiting measures following the regional currency crisis that had devastated the baht two years earlier — the July 1997 float is still considered one of the sharpest single-day currency collapses in Asian history. The 1000 baht denomination, already the highest in regular circulation, was accordingly given the most robust security specification in the series at the time of release.

The Bank of Thailand Note Printing Works has produced domestic currency since 1969, making Thailand one of relatively few Southeast Asian nations with fully sovereign in-house printing capacity for its entire circulating range. P#108 spans a five-year issue window, meaning plate and paper variations between early and late print runs are documented but not yet systematically catalogued.
