A digital gram is a claim on a specific, segregated, physically held gram. It is allocated, not pooled, and it is redeemable in metal. The IDCC certifies the holding and the register behind it, not the platform that sells it.

WHERE THESE FIGURES COME FROM
The Dīnār and Dirham weights are set by the classical standard commissioned under Sayyidunā ʿUmar ibn al-Khaṭṭāb (raḍiyallāhu ʿanhu), not by any mint. Minted bar and coin weights and finenesses are the full published catalogue of the mint, verified on 21 August 2026. Cast bar dimensions are PAMP Suisse's own published figures; PAMP states a single combined size and a separate thickness, so the combined figure is reproduced as printed rather than split across two columns.
Two dirham weights appear on this page, and both are correct. The fiqh dirham of 3.0618 g is the weight the rulings are built on: it fixes the silver nisāb at 200 dirham, or 612.36 g, and the mahr weights at 1,530.9 g and 1,469.7 g. It is a unit of the ruling, not a coin. The struck dirham of 2.975 g is what the mint actually presses, which is why a 10 Dirham piece weighs 29.75 g and a 20 Dirham piece 59.50 g. A single dirham is shown as 2.98 g in the table because the figure is rounded to two decimals; the piece itself is 2.975 g. Use 3.0618 g for zakāt and mahr. Use 2.975 g when you are weighing a coin.
The 400 oz bar is the LBMA Good Delivery format. The LBMA permitted dimensional ranges are a length of 250 mm ± 40 mm, a width of 70 mm ± 15 mm, a height of 35 mm ± 10 mm, and an undercut of 5° to 25°. The figures shown are one refiner's bars within those ranges, so a Good Delivery bar from another refiner will differ and still be conforming.
A dash means the mint does not publish that dimension for that piece. The IDCC does not estimate a dimension it has not been given.
A brief history of the Dīnār and the Dirham
Commissioned under Sayyidunā ʿUmar ibn al-Khaṭṭāb (raḍiyallāhu ʿanhu)
The weights on this page are not a modern invention. The Dīnār and the Dirham were standardised under the leadership of Sayyidunā ʿUmar ibn al-Khaṭṭāb (raḍiyallāhu ʿanhu), and it is that commission that fixes the Dīnār at 4.25 g of gold and the Dirham at 3.0618 g of silver. Every figure in the tables above descends from it.
All coins certified by the IDCC are struck in accordance with documented, Shariah compliant historical coinage commissioned under and during the auspices of Hadhrat ʿUmar al-Fārūq (raḍiyallāhu ʿanhu). The Islamic Monetary Council was founded on that precedent, and the Islamic Digital Certification Council continues to certify against it.
The history of the dinar and dirham in Islam is a fascinating journey through the development of Islamic currency, stretching back to the early days of the faith in the 7th century CE. The dinar, a gold coin, and the dirham, a silver coin, have played a crucial role in shaping Islamic economics, culture, and trade.
These coins found their beginnings during the time of the Prophet Muhammad. As Islam was emerging in the Arabian Peninsula, there was a need for a medium of exchange and a standard measure of value. At this early stage, the coins were relatively simple, often following the conventions of neighbouring Byzantine and Sassanian coinage.
The Umayyad Caliphate, the first major Islamic dynasty, was instrumental in standardising and expanding the use of the dinar and dirham. The Umayyads played a significant role in shaping the coins' design and aesthetics. They began featuring inscriptions in Arabic, a notable departure from earlier practices of using Greek or Persian scripts. These coins, adorned with Arabic calligraphy and geometric motifs, began to symbolise the economic and political might of the Islamic world.
The Abbasid Caliphate, which succeeded the Umayyads, continued the tradition of minting the dinar and dirham. Under their rule, the coins became even more intricate and visually appealing, with a focus on beautiful calligraphy and artistic embellishments. This period marked a time of prosperity, and the dinar and dirham became renowned as symbols of the Islamic economic and political power that stretched from Spain to India.
The use of the dinar and dirham was not limited to the Arabian heartland. They spread across the Islamic world, influencing regions as diverse as Spain, North Africa, the Indian subcontinent, and Southeast Asia. These coins were not just a means of exchange but also a manifestation of Islamic identity and prestige.
However, over time, as the Islamic world faced political fragmentation and economic challenges, the standardisation of the dinar and dirham began to erode. Local rulers and dynasties started to mint their own variations of these coins, leading to a loss of uniformity.
In subsequent centuries, the rise of the Mongol Empire and the dominance of the Ottoman Empire significantly altered the dynamics of Islamic coinage. The Ottomans introduced their own currencies, including the gold lira and the silver akçe, further diversifying the monetary landscape in the Islamic world.
During the colonial era, European powers introduced their currencies in regions under their control, contributing to the decline of the traditional dinar and dirham. In the modern era, many Islamic countries adopted fiat currencies, which are not based on precious metals.
The dinar and dirham continue to hold a special place in Islamic culture and finance, even if they are not widely used in their traditional form. They represent not just currency but a historical and symbolic connection to the early days of Islam and the economic and political prominence of Islamic civilisation.
What the IDCC will and will not certify
Are photos allowed on IDCC products?
IDCC does not provide compliance certification for coins, bars, or any assets featuring facial photography of humans or animals (eyes), in adherence to Shariah principles.
According to the Hadith, images with faces are discouraged, and IDCC products respect this Islamic tradition by abstaining from including such photos.
Are IDCC products always 24K, 999.9 fine?
IDCC issues Tayyib Certifications for gold and silver, and we are actively exploring certifications for copper, platinum, and other precious metals. The certificates clearly indicate the purity levels, including 18k, 22k, and 24k for gold, and similar specifications for other precious metals provided by IDCC.
Does the IDCC issue Tayyib Certificates for jewellery or other precious metals?
Yes. The IDCC supports the jewellery market by issuing Tayyib certificates, digital and physical, stating the purity, weight and specification of a piece. Beyond gold and silver this extends to copper, bronze, aluminium and platinum, and to set stones including diamond, ruby and emerald.
Aside from dinar and dirham, what are the IDCC issued bars and coins?
In adherence to our Islamic tradition and the commitment to the financial well-being and protection of our Ummah, IDCC believes in the investment and safeguarding of wealth. From Ramaḍān 1443, April 2022, IDCC's board established benchmarks and criteria for the creation of minted ingot bars and bullion bars. This decision was driven by the convenience with which gold and silver can be manufactured at refineries without the governmental banking hindrances associated with dinar and dirham. Our bars adhere to industry standards similar to those of the LBMA, UAE Good Delivery (which replaced Dubai Good Delivery in November 2021), and other recognised gold and silver precious metal marking sizes.
Are other Islamic branded coins considered dinar and dirham?
Historically, the 1 Dīnār coin has been equivalent to 4.25 g of gold. However, Dīnār coins have had varying weights in the past and were not always 4.25 g. Other minted coins adhere to industry standard weights of 4 g and 8 g and do not carry decimal weights. They are not officially considered Dīnār or Dirham.
Does the IDCC certify Digital Gold and Digital Silver?
Yes. From 30 August 2026 the Islamic Monetary Council and the Islamic Digital Certification Council accept Digital Gold and Digital Silver for certification, from a minimum unit of one gram of each. The metal behind a digital gram must be allocated rather than pooled, so that each digital gram corresponds to a specific, segregated, physically held gram, and it must be redeemable in metal. The IDCC certifies the holding and the register behind it, not the platform that sells it.
Why does Digital Gold start at one gram?
One gram is the smallest unit that can be tied to a specific piece of allocated metal and still be redeemed as metal. Below that a holding stops being ownership of a thing and becomes a claim on a pool, which is the arrangement the IDCC exists to distinguish itself from. The one gram floor applies to both Digital Gold and Digital Silver.
