50 Yuan Bank of Chinan

The Bank of Chinan (Chi-Nan Yinhang) was a Japanese puppet institution established in 1938 to facilitate economic control over occupied Shandong province. Its notes were designed to displace Chinese National Currency in the region, functioning as an instrument of monetary occupation rather than conventional banking.

The S3070 series encompasses several signature and color varieties; the "D" suffix distinguishes a specific combination that collectors have found notably harder to locate than the more common earlier variants. Wartime paper quality was inconsistent, and notes from this issuer frequently show foxing and brittleness — not mishandling, but a consequence of the inferior pulp stock available under wartime production constraints.
