Issued during the reign of King Bhumibol Adulyadej (Rama IX), this banknote reflects Thailand's monetary modernization in the late 1960s under the Bank of Thailand's administration. The note's primary imagery—the reigning monarch and the sacred Emerald Buddha temple complex—emphasizes both national sovereignty and the cultural-religious foundations of Thai identity during a period of significant political transition in Southeast Asia.
The obverse features a formal portrait of King Bhumibol Adulyadej (Rama IX) positioned on the right side, depicted wearing glasses and traditional Chakraphat-style formal Thai dress, facing forward with dignified bearing. The reverse displays a detailed engraved illustration of the Emerald Buddha Temple (Wat Phra Kaew) within the Grand Palace complex, characterized by multiple ornate spires with traditional Thai architectural features including curved roofs, golden elements, and intricate decorative details. Both sides employ elaborate Thai ornamental patterns and scrollwork borders, with the royal emblem positioned in the upper left of the obverse. The dominant color scheme utilizes red and maroon tones against cream and off-white backgrounds, creating strong visual contrast while maintaining the ceremonial dignity appropriate to royal portraiture.
Front side: 'ธนบัตรแบงค์ของประเทศไทย' (Banknote of the Kingdom of Thailand); '100' and 'ร้อยบาท' (One Hundred Baht); Serial number '91X887923' in upper left and lower right. Back side: '100' (Denomination) in lower left corner. All text rendered in Thai script and Arabic numerals according to standard Thai banknote convention.
Intaglio engraving (line engraving) on the Thai Banknote Printing Works presses, evidenced by the fine line patterns, intricate engraved detail visible throughout both the portrait and architectural elements, and the precise micro-line security patterns in the decorative borders. The quality of impression and sharpness of detail observed in this PMG 67 example is consistent with high-quality intaglio production standards of the Thai state security printer.
The observed example shows no Thai overprint on the face, consistent with the standard regular-issue variety (P-85a). The serial number format '91X887923' does not show the S-(W) replacement note prefix, indicating this is from the main regular printing run. PMG population reports indicate only one catalogued variant (P-85a) for this Pick number, suggesting minimal variety differentiation within the standard issue.
