100 Baht - Rama IX Revenue Department

Issued to mark the 120th anniversary of the Thai Revenue Department, founded in 1896 under Rama V as part of a broad fiscal modernization program that restructured royal finances along Western bureaucratic lines. By 2015, commemorative 100 Baht copper-nickel pieces of this weight had become a well-established format for Thai institutional anniversaries, with mintages typically kept modest and distribution channeled through the issuing agency rather than general circulation.
