| 背面描述 | A stylized carrack under sail, depicted heading left, is superimposed over Toscanelli's map. Three sailors are shown aboard the vessel, each bearing attributes of navigation and conquest: a rudder, a navigational chart, an astrolabe, and a sword bearing the cross of the Order of Christ. A legend describing the westward explorations arcs above the central design, while the dates 1452 and 1486, marking the chronological bounds of this period of Portuguese maritime exploration, appear below. |

This piece belongs to Portugal's long-running Descobrimentos series, which the government used to anchor national identity during the lead-up to the 500th anniversary commemorations of the major Atlantic voyages. The 1991 program focused on westward navigation — specifically the techniques and instruments that made deep-ocean sailing viable, a body of knowledge the Portuguese refined through sustained crown investment in the late 15th century rather than through any single dramatic event.
The .917 fineness places it in the 22-karat standard Portugal adopted for its commemorative gold program of this era, consistent across the Gomes R102 type variants.
