Description of obverse and reverse
The dinero was the currency of the Christian states of Spain from the 11th century. It was copied from the French denier and served in turn as the model for the Portuguese dinheiro.
In this coin King Alfonso VIII is depicted as a knight, riding on horse with a palm in his right hand.
In medieval times coins were used as powerful instruments of propaganda, being the best means to transmit the image of the king to the vast majority of illiterate citizenry.
A brief annotation
