| 背面描述 | The Portuguese armillary sphere overlaid with the royal escutcheon dominates the central field, rendered in bold relief against a plain background. The upper legend REPÚBLICA·PORTUGUESA arcs around the periphery, while the date 1958 and the word PROVA appear in the lower field, the latter indicating the pattern status of the piece. A beaded border frames the entire design, consistent with the obverse treatment. |

Portuguese India's days as a territory were numbered by the time these patterns were struck — Nehru's government had been demanding transfer of sovereignty since 1950, and Lisbon flatly refused. The patterns were prepared in anticipation of a coinage reform that never materialized; Goa, Daman, and Diu were seized by Indian military forces in December 1961, ending over 450 years of Portuguese presence before any new circulating series could be issued.
The alloy specified here departs from standard copper-nickel, incorporating a significant tin fraction — closer in character to a ternary coinage alloy than a conventional Cu-Ni blank.
