50 Đồng

This note belongs to the first unified currency series issued after reunification, when the Democratic Republic of Vietnam and the former Republic of Vietnam were brought under a single monetary system. The 1976 series replaced both the Northern đồng and the Southern đồng at a rate that heavily disadvantaged holders of Southern currency — 1 new đồng for 1 Northern đồng, but only 1 new đồng for 500 Southern đồng in cash holdings above minimal thresholds.

The exchange was as much a political instrument as an economic one. Printing was handled by facilities in the Soviet sphere, consistent with other notes in this series, though exact attribution between East German and Soviet printers for individual denominations remains a matter of some dispute among specialists.
