Currency continuity

Argentine peso — 1881–1985 continuity

FTM000057 · Research draft

Peso moneda nacional, peso ley and peso argentino are scale/name epochs, not three species.

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: 1881–1985; this does not establish the entire lifetime.
