1000 Yuan Bank of Shansi, Chahar, & Hopei

The Bank of Shansi, Chahar & Hopei — commonly called the Jinci Bank in Chinese sources — was a Communist-controlled regional bank established to finance operations in the Jin-Cha-Ji border region during the civil war period. The 1946 high-denomination issues like this 1000 Yuan were necessary responses to severe inflation eating through lower-value notes faster than they could be printed and distributed across guerrilla-held territory.

Border region currencies were explicitly prohibited from circulating in Nationalist-controlled zones, and Nationalist forces periodically conducted confiscation campaigns. Notes that survived did so largely by accident.
