Pick 43 is a transitional issue, released in 1975 as the North Vietnamese administration moved to consolidate monetary control following reunification. The National Bank of Vietnam had operated in Hanoi since 1951, but this series was designed to function across a newly unified territory where the southern đồng — backed by U.S. economic support — had been the circulating currency for two decades. The practical problem of absorbing two incompatible monetary systems into one was not fully resolved until the 1978 currency reform introduced the new đồng at brutal conversion rates.

Paper quality on surviving examples tends toward brittleness at the folds — a known characteristic of Vietnamese paper stock from this period.
