Depicts the coat of arms, legend "Government of Thailand", date and value around.

The Western-style coat of arms was created at the command of King Rama V. The armorial emblem contains almost all the elements of a European coat of arms; however, all the components of the emblem are traditional Thai royal symbols:

The escutcheon or shield, is divided into three quadrants. The first (chief) quadrant depicts an Airavata. This quadrant represents the Thai heartland, the three heads of the elephant represents its northern, central and southern regions. The lower left quadrant (dexter base) depicts a white elephant. This quadrant represents the Laotian suzerainty. The lower right quadrant (sinister base) depicts two-crossed krises (one with and one without a scabbard), this represents the Malay suzerainty in the south.

Above the shield is the symbol representing the Chakri dynasty, a disc and a trident (Chakra and the Trisula). The shield is then surrounded by the chain of the Order of the Nine Gems (representing Buddhism) with a chain and pendant from the Order of Chula Chom Klao (featuring a portrait of King Rama V).

The arms contains all the six Royal regalia of Thailand. The shield is crowned by the Great Crown of Victory, with a rays of light emitting from the top. Besides the shield are two seven-tiered Royal umbrellas of state. Crossed behind the shield is the Sword of Victory to the left and the Royal staff to the right. In front of them are the Royal fan and flywhisk (to the right and left, respectively). And finally on the compartment, a golden multi-layered royal seat, are the Royal slippers.

The supporters of the arms are two mythical creatures. To the left of the shield (dexter) is an elephant lion (a lion with a trunk) or a Gajasiha (คชสีห์). To the right of the shield (sinister) is the king of the lions, the Rajasiha (ราชสีห์). The two supporters represents the two ancient departments of Kalahom (Gajasiha) and Mahatthai (Rajasiha). The mantle around the arms is the cloak of the Order of Chula Chom Klao, tied with pink ribbons (pink being the colour of Tuesday, the day of King Rama V's birth).
