100 Yuan Bank of Chinan

The Bank of Chinan (齊南銀行) was established under Japanese-sponsored administration in Shandong Province, one of several regional puppet banks set up to manage occupied territories and displace Nationalist and Communist currency. The 1942 date places this note squarely within the period of intensified Japanese economic integration of northern China, when puppet bank issues were used deliberately to drain commodity resources and suppress locally trusted currencies.

S-prefix Pick numbers indicate this as a "special" or regional issue — the classification itself reflects how outside the mainstream banking structure these wartime instruments were. Survival rates vary considerably; Shandong saw heavy post-war currency purges.
