| Beschrijving voorzijde | Central field bearing the crowned Portuguese royal arms: a shield of quinas (five escutcheons arranged in a cross, each charged with five bezants) enclosed within a bordure of castles, all surmounted by a royal crown. The mint mark 'L' for Lisboa appears to the right of the shield within the inner circle. A beaded inner border separates the central device from the surrounding circular legend, which reads: + IOHANES 3 R P ET A D GVINE, identifying the issuer as João III, King of Portugal and the Algarves, Lord of Guinea. The coin is struck by hand, resulting in a slightly irregular flan with characteristic hammered surface texture. |

| Aanvullende informatie |
João III inherited a treasury strained by the enormous logistical costs of maintaining Estado da India, and his early coinage reforms reflected a persistent tension between the need for prestige silver and the practical demands of Iberian trade circuits. The tostão — valued at 100 réis — was the workhorse denomination for domestic and Atlantic commerce throughout his reign, though debasement pressure would mount steadily by mid-century.
The '-L' mint mark confirms Lisboa production. The Gomes 102 attribution places this among the first-type issues, distinguished from later variants by specific die characteristics that collectors and auction houses have used to separate early from transitional strikes since Gomes published his foundational reference.
