The Treasury Department will mint commemorative coins and medals for His Majesty King Maha Vajiralongkorn's coronation, with the most expensive, platinum medals priced at 1 million baht to set a new record.
Up to 1,000 platinum medals can be made, said Amnuay Preemonwong, director-general of the Treasury Department.
Others minted items include gold, silver and cupronickel coins; silver and copper medals; and medals attached to a ribbon band.
Gold and silver coins are priced at 40,000 and 5,000 baht, respectively, while copper medals will retail for 3,000 baht and medals with a ribbon band for 1,600 baht.
Cupronickel coins are the cheapest in the series at 20 baht, and up to 5 million of them can be produced, Mr Amnuay said.
Until now, the most expensive coin sold for 300,000 baht. It weighed 240 grammes and was 99% gold. It was used to mark the occasion of late King Bhumibol's 80th birthday.
The coins and medals are expected to be in high demand from the public, as such an auspicious occasion does not happen often, Mr Amnuay said.
The department has been granted royal approval for the commemorative coins' and medals' design. It now awaits enactment of a royal decree and ministerial regulations.
Finance Minister Apisak Tantivarawong will hold a press conference about the subscription period soon. The coins and the medals will be distributed after the coronation set for May 4-6.
Interested parties can make reservations at Krungthai Bank, Counter Service and the Treasury Department's coin exchange centres.
