The mintage of Belgian money is carried out by a directeur de la fabrication who is nominated by and responsible to the government.
The oldest known pieces are imitations of the Athenian mintage of the 4th century B.C., with the legend AOE and the owl standing on an overturned amphora.
The Gurkhas, however, in 1788 and following years continued to strike coins of progressively debased quality, which were rude imitations of the old Nepalese mintage, and to endeavour to force this currency on the Tibetans, eventually making the departure of the latter from old usage a pretext for war and invasion.
It advocates unity of the monetary system throughout the entire state, with strict integrity in the quality of the coin, and the charge of a seigniorage sufficient to cover the expenses of mintage.
The sixpence is a slightly scarce or " key " date, having the lowest mintage of any recent sixpence.
