2 Đồng Unissued

The National Liberation Front's 1968 currency series was prepared in anticipation of a political outcome that never materialized — a liberated southern administration capable of issuing its own money independently of Hanoi. These notes were never released into circulation. The series is sometimes attributed to printing in East Germany or China, though neither attribution has been conclusively documented, and the NLF left almost no paper trail on the production logistics.

Unissued survivors reached the West primarily through military and diplomatic channels after 1975. Pick R5 is among the scarcer denominations in the series.
