50 Yuan Bank of Chinan

The Bank of Chinan (齊南銀行) was a Japanese-sponsored regional institution established to facilitate currency control in occupied Shandong province. Notes like this 1942 issue circulated alongside — and were explicitly designed to displace — the legal tender of both the Nationalist government and the older provincial banks, part of a deliberate monetary destabilization strategy across occupied northern China.

The S-prefix in the Pick reference places this firmly in the specialized Japanese occupation issues, a category where survival rates vary enormously depending on how quickly Allied forces moved through a given area after 1945. Shandong saw protracted transition, and redemption of occupation currency was chaotic.
