1 Cash Hanyuan Tongbao

Issued under Liu Chengyou, the second and final emperor of Han, one of the shortest-lived of the Ten Kingdoms that fragmented northern China following the Tang collapse. The Han lasted barely four years before Guo Wei, a general Liu had attempted to purge, overthrew the dynasty in 951 and founded the Later Zhou. Coins of this reign are consequently scarce by default — there was simply no time to mint in volume.
