5 Yuan / 5 Yan Ta Chiang Bank / Dagiang Inxang

Ta Chiang Bank was a Communist-controlled regional bank operating in the Jiangsu-Anhui border area during the final years of the Second Sino-Japanese War. Notes of this type were issued under New Fourth Army administration — currency designed as much for political control of liberated zones as for ordinary trade. The infrastructure for stable printing was extremely limited in these guerrilla-held territories, and paper quality and registration consistency vary considerably across surviving examples.

Pick S3705 falls within a category of wartime Communist base-area notes that were rapidly demonetized and recalled after 1949 consolidation under the People's Bank, which is precisely why survivors in any condition are uncommon.
