1 Cash - Dading Tongbao, repeated inscription

The Dading reign (1161–1189) of Emperor Shizong was among the most stable periods of Jurchen Jin rule, and the coinage reflects it — large, well-organized minting operations supplied a cash economy that functioned across a vast north Chinese territory still absorbing former Song administrative infrastructure. The "repeated inscription" variety, in which the reverse carries a second rendering of the obverse legend rather than a blank field or single character, remains incompletely explained; it may indicate a secondary mint, a supervisory mark system, or simply a die-preparation anomaly that escaped correction.
