LXXX Reais 'Real Português Dobrado' - João III Single cross, Lisbon

Historical Context: This LXXX Reais, denominated the 'Real Português Dobrado,' was issued by João III, 'The Pious,' during the years 1555-1557. This period marked a critical juncture for Portugal, consolidating its vast maritime empire while facing new economic and political challenges. Minted in Lisbon, this substantial silver coin played a vital role in facilitating trade and state finance, reflecting the wealth derived from Portugal’s global ventures and the increasing demand for high-value currency in a burgeoning mercantile economy.

Artistry: While the specific engraver remains unrecorded, the coin’s design reflects the prevailing Iberian Renaissance aesthetic of the mid-16th century. The obverse typically features the crowned Portuguese royal arms, prominently displaying the five escutcheons (quinas) and castles, emblematic of the nation’s heritage. The reverse is characterized by a bold single cross, likely the Cross of the Order of Christ, a powerful symbol of Portuguese exploration and religious fervor, rendered with a simplicity that belies its profound cultural significance.

Technical/Grading: Struck in .9166 silver, weighing 7.3 grams and measuring 30 millimeters, this substantial coin often exhibits characteristic strike variations of the period. High points for wear and strike quality include the crown and central shield details on the obverse, and the terminations of the cross on the reverse. Collectors should look for full definition in the quinas and clear legends. Typical technical flaws may include minor off-centering, planchet irregularities, and variable strike pressure, which can lead to areas of flatness, particularly on the periphery.
