1 Yuan Bank of Eastern Chekiang

The Bank of Eastern Chekiang was a regional institution operating in Zhejiang Province during the final chaotic years of the Second Sino-Japanese War. By 1945, the province had experienced years of shifting Japanese occupation and Chinese Nationalist counter-pressure, and local currency issuance was fragmented among numerous provincial and county-level banks — each trying to maintain some functional exchange medium as hyperinflationary pressures from Chongqing's central government notes made the CNC dollar increasingly unreliable.

The S-prefix Pick classification places this firmly in the Chinese provincial and local issues category. Relatively little detailed documentation exists for this specific series variant, which is itself telling about how briefly and narrowly it may have circulated.
