10 Yuan Bank of Chinan

The Bank of Chinan (Jinan) was a regional institution operating under Japanese occupation authorities in Shandong Province following the fall of Jinan in 1937. Notes issued in 1939 circulated alongside — and in direct competition with — the older Chinese Nationalist currency the Japanese were systematically working to displace, a process that involved both flooding occupied territories with new paper and suppressing the old.

The Pick S3070 designation places this in the "S" — Special Issues — sequence, reflecting its status as a regional occupation-era emission rather than a central bank issue. Surviving examples frequently show heavy handling wear, consistent with active use in a wartime commercial environment where paper currency changed hands rapidly and was often reluctantly accepted.
