People who reserved commemorative coins for the occasion of the coronation of His Majesty the King will be able to receive the items from the start of next month.
The last day to order the coins was Friday. They are being produced by the Treasury Department under the Finance Ministry.
One side of the coin will display a portrait of His Majesty the King, while the other side will include his emblem.
Buyers had a choice of seven different types of commemorative coin: gold; silver; cupronickel; platinum; sandblasted, black-coated silver; black-coated copper as well as a special commemorative medal.
On display: Clay and plaster moulds of commemorative coins are placed side by side. The plaster casts will be coated with sillicone and epoxy to make new moulds that will be put into a machine to craft coins.
Glistening moment: A worker at the Royal Thai Mint handles a newly-minted coin.
In the works: A design of a coin with a portrait of His Majesty the King is seen on a computer screen.
The cheapest option was the cupronickel coin, at a price of just 20 baht, and the most expensive was the platinum coin, which buyers could reserve for 1 million baht.
All coins are being produced at the Royal Thai Mint in Khlong Luang district of Pathum Thani.
To make the coins, workshop staff start by making clay moulds of each coin. They then make plaster casts from the moulds, which are later coated with silicone and epoxy.
The epoxy moulds are then put into a machine that crafts the coins from the metal materials.
Festive preparations: A staffer examines a package of coins in preparation to deliver them to those who reserved the items.
