Northern Zhou of Northern Dynasty (557-581 AD), Emperor Jing di, Yu wen Chan, 'Yong Tong Wan Guo' (Yong = eternal, Tong = circulation, Wan = 10 thousand or every, Guo = country). 5.3g, Bronze, 29.76mm (Large type). This coin is one of '3 great beautiful coins of Northern Zhou'. For me, it's the most beautiful chinese ancient coin. UNC EF (there are no UNC for oriental cast coin. UNC EF, means from a hoard that apparently did not circulate). Scarce piece and very rare in this superb condition.
