The engraver's signature 'JJBRITO', the mint mark 'INCM', the fineness 'AU 999‰', and the troy weight indicator '1/20 OZ' appear in the lower portion of the field. |

| Additional information |
Afonso Henriques secured Portuguese independence through a combination of military campaigning against the Moors and persistent political pressure on the papacy, which finally recognized him as king in 1179 — over four decades after he had already declared himself one. The quarter-euro gold series launched by INCM in the mid-2000s placed him first in the sequence, a deliberate choice given his status as the kingdom's founder.
At 1.56 grams of .999 fine gold, these pieces were struck more as collectibles than anything approaching circulation issues.
