20 Ðồng

This note belongs to the first unified currency series issued after reunification — the September 1975 monetary reform had already replaced the currencies of both the former Republic of Vietnam in the South and the Democratic Republic of Vietnam in the North with a transitional dong, but this 1976 series consolidated that process under a single national bank identity. The State Bank's name appearing here reflects the institutional continuity from Hanoi rather than a new southern entity.

Pick 83 is among the lower denominations of the series and circulated heavily through a command economy with chronic shortages and suppressed pricing — actual purchasing power of a 20 dong note eroded quickly through the late 1970s, well before the 1985 redenomination cut the dong at 10:1.
