1 Chiao / 10 Cents Bank of Chinan

The Bank of Chinan was a regional bank established under the Japanese-sponsored Reformed Government of the Republic of China, which controlled parts of Jiangsu, Zhejiang, and Anhui provinces from 1938. These small-denomination notes were issued specifically to facilitate low-value transactions in occupied territories where existing Chinese currency was being systematically displaced — not a central banking operation in any conventional sense, but an instrument of economic administration under occupation.

The "b" suffix on S3064 typically denotes a color or signature variant within the series. Provincial puppet-bank notes of this type were often printed in multiple variants over short windows, and survival rates vary considerably between them.
