The 723 Umayyad Gold Dinar

The 723 Umayyad Gold Dinar is one of the most valuable Islamic coins. The gold dinar is an Islamic medieval gold currency initially minted by Caliph Abd al-Malik ibn Marwan in AH 77 (696–697 CE). The dinar is 1 mithqal in weight (4.25 grams or 0.137 troy ounces). The coin is the earliest Islamic currency to specify a place in Saudi Arabia, and it contains the inscription "mine of the commander of the faithful." Experts estimate that about a dozen specimens of the coin exist.

The 723 Umayyad Gold Dinar sold for 3.7 million pounds (about $6 million) at auction in 2011, making it the second most expensive coin ever sold at auction. Another variant of the coin was sold at the same price in pounds in 2019, however the dollar value was almost $4.8 million.
