5 Dollars - Charles III Mount Kailash

Mount Kailash in Tibet has never been climbed — not because it's technically impossible, but because the Chinese government has kept it closed to mountaineers since 2001 at the request of religious groups. It is considered sacred in four religions: Hinduism, Buddhism, Jainism, and Bon. Niue has issued collector silver in large formats like this for decades under licensing arrangements, functioning essentially as a mint-for-hire for themed series with no connection to the issuing territory.
