5 Chiao Meng Chiang Bank

The Meng Chiang Bank was established in 1937 by Japanese occupation authorities to serve Inner Mongolia — a puppet financial institution underpinning the nominally autonomous Mongolian Military Government. Its coinage replaced Chinese Nationalist currency as part of a deliberate economic separation of the region from the Republic of China. The 1938 issues were among the earliest struck for the bank, produced almost certainly at the Osaka Mint under Japanese supervision.

JNDA attribution places this squarely within the occupied-territories coinage documentation compiled by Japanese numismatic researchers, a reference set that remains the authoritative source for these wartime puppet-state issues.
