| Comments |
The B-series military currency was introduced in 1945 specifically to replace the yellow-seal "Hawaii" notes and the standard Federal Reserve issues then circulating in the Pacific theater. The "B" prefix on the serial numbers allowed occupation authorities to demonetize any currency that had fallen into Japanese hands — or been looted, counterfeited, or stockpiled — simply by declaring the previous series void.
This 50 Sen denomination sits at an odd economic threshold: the Sen had been effectively worthless under wartime inflation, yet occupation planners retained fractional denominations to stabilize retail trade during the transition to postwar price controls.
