5 Baht - Rama IX Queen Sirikit, FAO

Historical Context: Issued in 1980, this 5 Baht coin encapsulates the era of King Bhumibol Adulyadej (Rama IX), Thailand's longest-reigning monarch, a period marked by profound national development and stability. The coin specifically honors Queen Sirikit and her extensive work in rural development, particularly through the promotion of agriculture and handicrafts. The inclusion of the Food and Agriculture Organization (FAO) of the United Nations emblem underscores Thailand's commitment to international cooperation in food security and agricultural advancement, aligning with Rama IX's philosophy of a "sufficiency economy" and sustainable resource management during a period of rapid modernization.

Artistry: The design, originating from the Royal Thai Mint, reflects the characteristic style of modern Thai commemorative coinage. The obverse typically features a dignified, realistic effigy of King Rama IX, executed with precise detail. The reverse, dedicated to Queen Sirikit and the FAO, would incorporate a portrait or symbolic representation of Her Majesty alongside the distinct FAO emblem, likely surrounded by motifs representing agricultural abundance or traditional Thai craftsmanship she championed. While specific engravers are rarely publicly attributed for such issues, the aesthetic adheres to official royal portraiture and clear, symbolic iconography, ensuring both reverence and thematic clarity.

Technical/Grading: Struck in copper-nickel clad copper, this substantial 30mm, 12g coin presents distinct high-points for grading. On the obverse, critical areas for wear assessment include the highest points of King Rama IX's hair, ear, and the definition of his regalia. For the reverse, the intricate details of the FAO emblem, any delicate lines in Queen Sirikit's effigy (if present), and the crispness of any agricultural motifs (e.g., rice stalks, fish) are paramount. The large fields are susceptible to bag marks, while the cladding structure should be inspected for any signs of delamination or edge separation revealing the copper core. Full, unbroken luster across the fields and devices is crucial for uncirculated examples.
