5 Yuan Bank of Chinan

The Bank of Chinan (Jinan Bank) was established in 1938 under the Reformed Government of the Republic of China, the Japanese-sponsored collaborationist administration set up in Nanjing to govern occupied territories in central China. Notes from this issuer circulated in competition with both Nationalist currency and the older notes of pre-war Chinese banks — the occupying authorities needed local paper money to function but faced persistent public distrust of collaborationist issues.

The S3069 and S3069A distinction typically reflects a signature or overprint variant rather than a fundamental design change, though documentation on the precise differentiating characteristic is inconsistent across standard references.
