Xiao Zong - Chinese Collection

4-03: Southern Song Dynasty (1127 - 1279 AD). Emperor Xiao Zong (1163 - 1190 AD). Obverse 'Chun Xi tong bao'; clock-wise, in 'Regular' script. Reverse crescent above and dot below. I believe this might be the small character variety, part of this might be because I can't tell the difference between the 6 & 7 stroke 'bao' (any help would be appreciated). Therefore Hartill # 17.186 to 17.188 with the latter being the small character type. FD1198, S725 for the general type.
