100 Yuan Bank of Rehher Sheeng, brown, front proof

The Bank of Rehher Sheeng — a romanization of 熱河省銀行, the Provincial Bank of Rehe — operated in one of the more contested administrative zones in postwar northern China. Rehe Province itself was a Japanese-created entity absorbed into Manchukuo in 1933; after 1945 it became a flashpoint between Nationalist and Communist forces before being abolished entirely in 1955. A 1946 provincial bank note from this issuer exists in a narrow window between Japanese surrender and full-scale civil war intensification.

The "front proof" designation matters here — this was never a circulating piece. Tung Pei Hifan's production records for this series are poorly documented, and unlisted Pick status means auction appearances are the primary reference points for researchers.
