Gold, silver and 20-baht coins mark Queen Suthida’s 48th birthday

Thailand’s Treasury Department will begin selling and exchanging three types of commemorative coins on November 6, 2026, to mark the fourth-cycle, or 48th, birthday anniversary of Her Majesty Queen Suthida Bajrasudhabimalalakshana on June 3, 2026.

The collection, produced by the Ministry of Finance through the Treasury Department, comprises gold, silver and copper-nickel coins. Prices range from 20 baht for the standard commemorative coin to 99,999 baht for the limited-edition gold version.

Deputy Prime Minister and Finance Minister Ekniti Nitithanprapas explained that the coins were created to honour the Queen’s dedication to royal duties and her contributions to public welfare.

He noted that Her Majesty had undertaken numerous royal responsibilities with diligence and ability, helping improve people’s well-being while demonstrating exemplary conduct.

The commemorative issue is also intended to promote recognition of the Queen’s royal contributions in Thailand and abroad, while giving members of the public an opportunity to collect the coins as a tribute to Her Majesty.

Coin designs reflect royal duties and decorations

The front of each coin features a portrait of Her Majesty Queen Suthida wearing earrings and traditional Thai royal attire.

Her Majesty is depicted wearing the sash of the Most Illustrious Order of the Royal House of Chakri, together with a diamond-encrusted brooch and several royal decorations.

These include the insignia of the First Class of the Order of Chula Chom Klao, the First Class Royal Cypher Medals of Kings Rama IX and Rama X, and the Gold Ratcharuchi Medal of King Rama X.

Her Majesty’s full royal name is inscribed along the lower edge of the coin.

The reverse features portraits of Their Majesties the King and Queen undertaking royal duties associated with four development initiatives.

These are the Bueng Si Fai commemorative development project, Prem Prachawanarak Park, the Bo Din Khao Pond Development Project and a large-scale groundwater supply project designed to address drought.

An inscription around the upper edge commemorates the Queen’s fourth-cycle birthday anniversary on June 3, 2026, and identifies Thailand as the issuing country. The denomination of each coin appears along the lower edge.
