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:
"Om is a sacred symbol and sound that is known as the vibration of the universe. Found in ancient Hindu texts, Om has been used for centuries in prayers and ceremonies. This Om one gramme gold minted bullion bar can serve as a precious gift or secure investment and it has been tested and authenticated through an independent quality assurance process. Drawing on more than 1,100 years of minting expertise, we have applied our craft to ensure we faithfully represent Om, the sacred symbol and sound of the universe."
The bar is "minted" (struck using minting techniques similar to a coin, and not cast in the way that larger investment products are).
