The Revelation Bao Tong of the Ming Dynasty contains the mother money of the Eleven Beams.
Revelation Bao Tong, Zhu Youxiao, Emperor Xi of the Ming Dynasty, minted coins during the apocalypse (A.D. 1605- 1627). There are more than ten kinds of casting styles, including 10% off the bare back, 10% off the top and bottom of the back, and 10% off the back of "Zhen" and "Eleventh Two". Among them, there are three types of mother coins: "Eleven Twelve", "Secret Eleven Twelve" and "Sun Moon Pattern Eleven Twelve". These mother coins have deep mouths, clear strokes and no adhesion. This is a rare fine casting with Fiona Fang outline, thick and well preserved.
