100 Baht THB Banknote (Standard Issue) 2025

100 Baht Baht / Tical (Issued 2025)

A deep crimson and rose-pink wash floods every corner of this 2025 Thai hundred-baht note, making it one of the most vividly coloured banknotes in active circulation anywhere in Southeast Asia. At its heart sits a formally composed portrait of King Vajiralongkorn (Rama X), rendered in finely engraved intaglio lines that bring extraordinary depth to his military dress uniform and decorative chain of office. The note’s rich tonal palette — shifting from bright magenta at the edges to softer blush tones across the central field — gives it an immediate visual authority that distinguishes it from earlier issues in the series.

On the front, the central portrait of King Vajiralongkorn, the reigning monarch of Thailand, dominates the right-hand portion of the note. He is depicted in a dark military uniform adorned with epaulettes, medals, and a formal insignia collar, all rendered through precise intaglio engraving with subtle tonal shading that gives dimension to the fabric folds and decorative metalwork. To the upper centre, Thai script text identifies the issuing authority as the Bank of Thailand, with a secondary line of Thai script text beneath confirming the denomination as one hundred baht. The numeral “100” appears in deep red in the lower right corner, accompanied by a stylised floral security element rendered in gold and red tones. A vertical serial number reading “1H1520813” is printed in red along the right margin, with a horizontal serial number in red also appearing across the upper portion of the note. To the left of the portrait, an elaborate guilloché rosette forms the centrepiece of the security design, incorporating fine interlocking geometric lattice patterns in pale pink and crimson. A repeating micro-dot background pattern fills the surrounding field. Two facsimile signatures appear beneath the central text block, printed in dark ink. The lower margin carries a line of Thai script text referencing the monarch’s biographical details and the Buddhist Era date. A see-through registration feature is visible on the left-hand side, and a vertical security thread is embedded within the paper, becoming partially visible as a dark stripe running through the guilloché zone.

The reverse presents a richly detailed double portrait composition at its centre, depicting two Thai monarchs from earlier eras shown side by side in formal military attire with medals, sashes, and epaulettes. Based on the standard design of the 100-baht denomination, these figures are King Chulalongkorn (Rama V) on the left and King Vajiravudh (Rama VI) on the right, both engraved with considerable detail in the same intaglio tradition as the obverse portrait. Behind them, guilloché patterns radiate outward in soft crimson and rose tones, framing the portraits within an oval halo effect. To the upper left, a Garuda emblem — the national symbol of Thailand — appears above the numerals “100” set within a red-outlined denomination block. The lower left corner carries the large Thai numeral for one hundred rendered in deep crimson against the background pattern. Background vignettes flank the central portraits: to the left, a historical street scene featuring early motorised vehicles and buildings rendered in pale engraved linework; to the right, a mounted figure on horseback is visible in similarly fine engraved detail. A line of Thai script text runs across the lower margin of the reverse, presenting the standard legal tender and counterfeiting warning notice. The overall colour palette of the reverse mirrors the front, with warm rose-pink tones dominating and deeper crimson accents reinforcing the denomination text and principal design elements.
