The Thailand Gold Baht coins have been minted for centuries ago although minting of legal currency for circulation in gold halted in 1895 when the last coins made of gold were last struck. However, the striking of commemorative coins resumed in the 1946 and continued until 2016. Thus, the coins that are available currently are commemorative and in different denominations from 100 Baht.

The most popular commemorative Thailand Gold Baht coin is the issue that was released to mark Queen Sirikit’s thirty-sixth anniversary in 1968. They were issued in denominations of 150 Baht, 300 Baht, and 600 Baht. They weigh 15.04, 7.5 and 3.75 grams respectively with 27mm, 21mm, and 17mm in diameter in the same order. All the coins have a gold fineness of .900. They all have the bust-size effigy of Queen Sirikit facing to the right and surrounded by the text, “สมเด็จพระนางเจ้าสิริกิติ์ พระบรมราชินีนาถ พระชนมายุครบ ๓ รอบ” on the obverse. The reverse contains the inscription, “รัฐบาลไทย ๑๒ สิงหาคม พ.ศ.๒๕๑๑ ๑๕๐ บาท” surrounding the fruited wreath that engulfs the crowned monogram.

In 1971, the 5000 Baht Thailand Gold Baht commemorative coin was issued in celebration of the White-eyed River Martin. It has a gold weight of 33.4379g, a diameter of 33.4370mm and a purity of .900. In 1981, Thailand also issued another commemorative Thailand Gold Baht coin in the denomination of 4000 Baht to commemorate the UNICEF Year of the Child. The coin has a diameter of 27mm and weighs 17.17g. It has a gold content of .900 and an actual gold weight of .4983 troy ounces. The obverses of these two commemorative issues have the effigy of Rama IX (King Bhumibol Adulyadej) wearing spectacles and facing slightly to the right. The reverses of the 1971 5000-Baht and the 1981 4000-Baht issues feature the respective images of the White-eyed River Martin in flight and two children playing.

The Bureau of Royal Thai Mint mints all Thailand Gold Baht coins. The Mint was founded in 1860 and has its headquarters in Pathum Thani. Investors and collectors who trade in the Thailand Gold Baht are exempt from sales tax or VAT.
