Manufactured by WANG HING in the late 19th to early 20th century. The shape resembles that of ancient Chinese currency, with a hole in the center representing the sky, the round shape symbolizing the Earth, and various other symbols. This is indeed one of the essences of WANG HING & Co, which made traditional Chinese silver pieces portable after the signing of the Treaty of Nanking in 1842. Overall good condition - See photos.
