Almohamad Square Dirhem Fine
These curiously shaped square silver dirhams were struck by the Almohad Caliphate, founded by Ibn Tumart, a member of the Masmuda, a Berber tribe that controlled much of Northern Africa and Spain at the time. They were struck between 1121-1269 AD making them around 800-900 years old and have Arabic script on both sides showing mint marks and declarations of faith but are undated and anonymous, meaning that they are not attributable to any single ruler. The square shape was probably symbolic and linked to the emergence of the Square Kufi c script that emerged in the 12th century, influenced by Iranian architecture. They certainly weren’t the first to strike square coins as the Indo-Greeks had done this over 1000 years before but since these dirhams are also quite thin, one practical reason for their shape would be to make it easier to cut them from a larger flat piece of metal.
