Mother Coins 母錢 in old Chinese coin making
During the Han Dynasty, Chinese mints partially solved the inconsistencies in cast coins by using bronze master moulds. Master moulds were used to prepare the clay moulds which will be used for the actual casting.
Mother coins are pressed on the wet sand in the wooden frame (first half of the mould). Rods are placed between the coins to create channels where the molten metal can flow. A second frame (second half of the mould) is placed on top and pressed tightly. This imprints the designs of the obverse and reverse of the mother coins on the sand in the frames.
Obverse: Hsuan-T'ung type.
Reverse: "BOO" on the left and "CIOWAN" (Board of Revenue mint) on the right.
Normally seen nearly "as cast" but are normally roughly finished.
The use of cast cash coinage all but came to an an end shortly after 1912, so these Hsuan-T'ung coins saw little use and are normally seen in a grade of XF to near mint state condition with clear original file marks. Coins appearing to grading F or VF are usually just poor castings rather than worn coins.

He was only three years old when he come to the throne, then was forced to abdicate to the forces of the Republic 1912, but continued to live in the Imperial palace until 1924.
