10 Yuan Bank of Pei Hai

The Bank of Pei Hai — Beihai Bank — was a Communist-administered regional bank operating in the Shandong-Bohai base area during the latter stages of the Second Sino-Japanese War. It issued its own currency in direct competition with both Japanese military scrip and Nationalist-backed notes, deliberately supplanting them in territory under CCP control. The 1945 issues were part of a broader effort to stabilize exchange within the liberated zones and gradually absorb earlier, less controlled local currencies.

Pick S3580A places this within a suffix-classified variant, suggesting multiple plate or printing runs exist within the type — not uncommon given the decentralized wartime production conditions these notes were printed under.
