Four crude Chinese characters (regular script) Xiang Fu Yuan Bao / Manchu characters Boo Chiowan. 25mm, 4.06 grams. Issued in the 18th century or slightly later. Not properly studied and seems unpublished. cf. Zeno #52047 / 82628 / 83465.
The reverse is cast at 90 degree rotation RIGHT compared to the obverse.
The obverse of these coins is copied from the Xiang Fu Yuan Bao cash produced by Emperor Zhen Zong (998-1022) of the Northern Song dynasty. The Manchu reverse is copied from the Qing dynasty cash from the Board of Revenue mint. These very rare and unusual coins are found in Indonesia, though (very strangely) it seems that a few coins of this type were unearthed in the Lugansk area in Ukraine (see Zeno #81628 and 83465). The coins are very crudely produced and cast in tin or brass alloy of some sorts. The coins were never properly researched and remain very rare. We do not know which of the Indonesian (or possibly Malaysia) Kingdoms produced these coins.
