Huan Zong - Chinese Collection

4-04: Tartar Dynasties; The Western Xia (1032 - 1227 AD). Emperor Huan Zong (1194 - 1206 AD). Obverse: 'Tian Qing yuan bao', clock-wise; Note: similarity seen with H# 18.22 but 'Qing' appears to better fit this attribution. Reverse: poor preservation all around but I almost make out a Crescent above. If the attribution is correct, that places this coin in a scarce to very scarce category, assistance welcome. Hartill # 18.106 or 18.107; FD1691/92.
