4 Annas Piardoba Army Air Base

Piardoba, in Bengal's Murshidabad district, was a major USAAF base during the CBI — China-Burma-India — theater, primarily hosting B-29 Superfortress units of the XX Bomber Command between 1944 and 1945. Officer's club scrip issued at such bases substituted for rupee currency within the mess and bar, partly to manage exchange-rate complications and partly to prevent local currency from leaving the base economy.

The anna denomination — a sixteenth of a rupee — reflects direct adaptation to the subcontinent's pre-decimal coinage structure rather than any dollar equivalent. Few CBI base scrip pieces survive; most were redeemed, destroyed at drawdown, or simply discarded when the base closed after Japan's surrender in August 1945.
