The Gold Imitation Dinar of King Offa

This coin is both one of the rarest (a single coin) and the most odd. It is a contempary copy of a gold dinar of the Caliph al-Mansur ruler of the Islamic Abbasid dynasty (a Islamic civilization based in Persia but with influence in the Mediterranean).

The name OFFA REX (king Offa) has been added (upside down!). The nature and pupose of the coin is uncertain. It has been postulated the is was to be a gift to the pope but with the Arabian script containing the phrase 'there is no God but Allah alone' this seems less likely!

It is in the British Museum. Click this link to view the coin.
