Watch List notes:

China: Qing Dynasty (1644-1911 CE), coin-shaped charm with square central hole, obverse inscribed four unknown characters, reverse inscribed 'Wu yue wu ri wu shi', 27.7*2.1mm, 8.5g. Extremely fine, rare. Note: Chinese numismatist Sun Zhonghui once appraised this coin as "a coin with all characters on obverse containing the component of Ku, identical to the invented characters used by members of Heaven and Earth Society, hence described by Ma Dingxiang as membership token of the secret society with unknown characters, except that the reverse inscriptions are different, only two specimens said to exist, therefore extremely rare and precious". The specimen in the Burger collection is in perhaps the finest condition..

Estimate: 7000 - 9000
