1 Dinar 917 is a bullion gold coin made from 4.25 grams of 22k gold and minted by Nubex. A Gold Dinar is a gold coin first issued in 77 AH (696-7 CE) by Caliph Abd al-Malik ibn Marwan.

The name dinar is derived from denarius, a Roman currency. The modern gold dinar made from 4.25 grams of 22-carat.

While pure gold is 24 carat, 916 means it is 22 carat. That is 91.6% pure gold and the rest includes metals like copper and silver. Metal in its purest state is very soft and impractical for making jewels.

To create jewelry that is practically wearable, gold has to be alloyed with other harder metals in the required proportions to make it malleable and durable.
