South Vietnamese đồng
CUR-V22-SOUTH-VIETNAM-DONG · Research draft
A documented account-unit or currency-system transition supports this predecessor identity; not admitted from a specimen or inherited label alone.
One scoped currency identity. Changes to subdivisions, scale, standard, instruments or issuers do not by themselves create children. A distinct account unit can remain a successor.
Dated observations: 1954–1978; this does not establish the entire lifetime.
