| Reverse description | Central field features a large Roman numeral 'X' denoting the denomination of ten réis, flanked by two six-pointed star ornaments in the field. Arranged around the X are groups of pellets representing the quinas of Portugal, disposed in the four quadrants formed by the arms of the numeral. The design is enclosed within a plain inner circle, itself surrounded by a circular Latin legend reading the royal title. The entire composition is executed in the hammered style typical of Portuguese copper coinage of the reign of Sebastião I. |

| Additional information |
Sebastião I was three years old when these coins were struck in his name. Portugal was governed by his grandmother, Catherine of Austria, acting as regent — a Habsburg by birth and deeply cautious in her administration. The "L-G" privy marks identify the Lisbon mint masters active during this regency window, a detail that places the coin precisely within those transitional years before Sebastião assumed personal rule in 1568.
The X Reais denomination in copper served the lowest register of daily exchange during a period when Portugal's Atlantic trade was generating enormous silver and gold wealth — wealth that rarely reached domestic copper circulation.
