One of the rarest coins in the world which dates back to 723AD is set to sell at an auction for £1.6million.
The gold dinar dates back to the Umayyad era and was made from gold mined at a location owned by the Caliph- one of the successors to the Prophet Mohammed.
The coin has several Islamic inscriptions and is almost the same size as a modern-day British £1 coin.
It is set to sell with auctioneers Morton & Eden in London on October 24.
They have given it their highest ever pre-sale estimate of between £1.4 and £1.6million.
The text on the coin translates as 'Mine of the Commander of the Faithful' as well as other religious text.
The gold mine is believed to be located between the two Holy Cities of Mecca and Al Madinah, in the west of present-day Saudi Arabia.
About only 12 of these coins are known today and are almost all now held in international museums or private collections.
