20 Baht - Rama X Princess Galyani Vadhana

Historical Context: Issued in 2023, this 20 Baht coin from Thailand falls within the reign of King Maha Vajiralongkorn Phra Vajiraklaochaoyuhua (Rama X), who ascended the throne in 2016. It commemorates Her Royal Highness Princess Galyani Vadhana, King Rama IX’s elder sister and Rama X’s aunt. The 2023 mintage likely marks the centenary of her birth in 1923, reflecting the Thai tradition of honoring revered Chakri dynasty members through numismatic issues. Its copper-nickel composition is typical for a higher-denomination commemorative.

Artistry: The design adheres to the refined aesthetic characteristic of the Royal Thai Mint. While specific engraver signatures are not typically prominent, the stylistic school emphasizes dignified royal portraiture. The obverse features a contemporary effigy of King Rama X, rendered with classical precision. The reverse depicts Princess Galyani Vadhana, likely a mature portrait, surrounded by inscriptions detailing denomination and date. The overall execution balances regal formality with intricate detailing, incorporating subtle traditional Thai motifs relevant to the Princess's life.

Technical/Grading: For optimal grading, attention should be paid to the highest points of relief, most susceptible to wear or contact marks. On the obverse, these include the King’s hair, ear, and raised elements of his uniform. For the reverse, critical areas are Princess Galyani Vadhana’s hair, cheekbones, and fine details within her regalia or surrounding design. Preservation of original mint luster across the fields and absence of bag marks or rim dings are paramount for achieving top-tier uncirculated grades on this 15-gram, 32mm copper-nickel issue.
