100 Yuan Bank of Chinan

The Bank of Chinan (Jinan Bank) was a Communist-controlled regional bank operating in the Shandong-Jiangsu border area during the Second Sino-Japanese War. Its notes circulated in liberated zones as the CCP's answer to both Japanese military scrip and Nationalist fabi, deliberately undercutting both by maintaining tighter controls on issuance than the Chongqing government managed with its own currency.

By 1944 the bank was printing higher denominations to keep pace with wartime inflation eating through smaller notes. S3084A is one of the scarcer regional variants within the series — the suffix letter distinctions in this Pick group reflect plate or printing differences that remain incompletely documented.
