50 Yuan Bank of Chinan

The Bank of Chinan (Jinan Bank) was a Communist-controlled regional bank operating in Shandong province, established in 1938 under the Jiaodong Administrative Office. By 1945, the bank was issuing currency to support the Eighth Route Army's operations and administer liberated zone economies — these notes functioned as instruments of wartime economic control as much as conventional currency.

The S-prefix Pick designation signals a regional or special issue, and the B suffix variant distinction likely reflects a block letter or printing plate difference. Attribution of these notes can be complicated by inconsistent surviving documentation from the issuing authority itself.
