| Additional information |
Afonso Henriques, who became Afonso I following his victory at Ourique in 1139 — the battle after which he declared himself King of Portugal — issued this coinage as part of an immediate assertion of independent royal authority. Portugal had been a county under Leonese suzerainty; the dinheiro was among the first instruments of a monetarily sovereign, if still militarily precarious, new kingdom.
The billon composition reflects the chronic silver shortage that plagued Iberian minting throughout the twelfth century, a consequence of the ongoing Reconquista disrupting trade networks.
