The Royal Mint of the United Kingdom, which makes the country's circulating coinage, is also very active in the bullion coinage space and issues many bullion coins which are legal tender.
Additionally, it also makes bullion which is not legal tender and is targeted at investors and not at coin collectors - such as this one.
The Royal Mint says about this product:
"The Kaaba is the direction of worship for Muslims all over the world and is regarded as the holiest place on Earth. Located near the centre of the Great Mosque in Mecca, the Kaaba is unmistakable in shape and it is covered by the Kiswah, a black cloth embroidered with gold decoration. This year, and for the first time, the Kaaba is being represented on a Sharia-compliant 20g gold bullion minted bar from The Royal Mint.
Esteemed for its beauty and treasured for its value, gold has long been seen as a precious gift. Tested to rigorous standards by an independent quality assurance process, the Kaaba gold bar will make a thoughtful gift for a festival, wedding or other special occasion. Applying more than 1,100 years of minting expertise, we have crafted a beautiful representation of the Kaaba, the holiest site for millions of Muslims." |
