“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.
Emperor MU TSUNG
Mu Tsung is unusual amongst Ch'ing dynasty emperors in that he had two reign titles, although one of them was only in use for a very short period of time (probably a few weeks).
Reign title: CH'I-HSIANG, AD 1861Coins of this reign title are very rare and most if not all examples are either seed or mother cash. Hartill (page 393) says he does not believe any circulation examples were cast, and only lists examples from Board of Works and Board of Revenue mint. Schjoth did not list any examples.
