The Ultimate Thai Ancient Coin, King Chulalongkorn's equal Somdet P'ra Deb Sirindhra (Princess mother), to commemorate his age. The date chosen 24 May 1880 was very symbolic because in that year the King's age was equal to his mother's at her time of passing. Attendees who were present during the ceremony were given examples of this issue, while full sets were given to royalty and high ranking officials. Two of the three markings are typical emblems of Thai coinage and medals. One being an elaborate form of the chakra, and the other is the mark of the crown. The third mark is that of Rampeui with date below, which was chosen because it was his mother's maiden name. The Chang (80 Baht) and 1/2 Chang (40 Baht or 10 Tamlung) differ significantly from most other Thai bullets in that they are intricately hand engraved as opposed to the smaller denominations where all of the marks are struck. Even further delineating from the norm is the fact that this series represents the first dated silver coins of Thailand and the only dated bullet coinage ever produced. Considered by most collectors and scholars to be the pinnacle of Thai numismatics, to obtain a single example of any denomination is a feat and is highly prized by collectors. We note another example of the 80 Baht of this type that sold for approximately $285,000 (9,520,200 Baht) in a 2018 auction in Thailand), seldom do the large examples from this series appear on the market and as such should be considered of the HIGHEST RARITY.
Ex: Eurseree Auction # 31 March 23-24, 2013 Lot # 1814 (part of) where the set hammered for an impressive 9,200,000 Baht (Approximately $288.6 thousand)
